The method provides a comprehensive test for preimplantation genetic diagnosis (PGD) of single gene defects. It can be used where there is a risk of severe genetic disorders being inherited from parents. A couple could have a family history of a genetic disorder or have had a child with a genetic disease. PGD screening with karyomapping can be used to identify embryos that do not carry defective genes and can be safely implanted. Infinium Karyomapping Assay Protocol The Infinium Karyomapping Assay utilizes SNP array technology. It consists of whole genome amplification using the SureMDA DNA Amplification System, BeadArray analysis using HumanKaryomap-12 (v1.0) DNA Analysis Kit, scanning with iScan System, and analysis/reporting using BlueFuse Multi software. The first stage of the karyomapping assay uses the SureMDA DNA Amplification System to amplify DNA from blastomere and trophectoderm biopsied cells to quantities suitable for use in the Infinium protocol. During the second stage of the karyomapping assay the SureMDA amplified DNA from the embryo biopsies, together with parental and reference genomic DNA, is prepared and hybridized to the HumanKaryomap-12 BeadChip. The Infinium protocol uses the DNA Analysis Kit and features single-tube preparation and whole-genome amplification, hybridization to the BeadChip, and a two- step allele detection process using labeled nucleotides. The complete Infinium Karyomapping Assay, which includes the SureMDA amplification protocol together with the Infinium Assay, can be performed within 24 hours. Audience and Purpose This guide is for laboratory technicians running the Infinium karyomapping assay. The guide documents the laboratory protocols associated with the assay. It is important that all sections of this protocol are read before starting the assay. Follow all the steps in the protocol in the order shown. 2 Part # 15052710 Rev.B Illumina provides the following tools for sample tracking and guidance in the lab: } The Lab Tracking Form guides you through the protocols with minimal illustrations and explanatory notes and includes user-entry fields for tracking progress and recording lot numbers, barcodes, and time metrics.

RELATED TRAINING For more guidance on setting up an Infinium laboratory, see the Infinium, Lesson 1: Lab Setup and Best Practice training video on the Array Online Training page of the Illumina website. 6 Part # 15052710 Rev.B Safety Precautions Safety Precautions CAUTION Only qualified laboratory personnel can perform the protocols described in this guide. Exercise caution when handling biological samples to avoid crosscontamination among pre-amp and post-amp samples. WARNING This protocol uses an aliphatic amide (formamide) that is a probable reproductive toxin. Personal injury can occur through inhalation, ingestion, skin contact, and eye contact. For more information, consult the safety data sheet for this assay at support.illumina.com/sds.ilmn. Dispose of containers and any unused contents in accordance with the governmental safety standards for your region. WARNING Buffer DLB contains potassium hydroxide: corrosive, harmful. Risk and safety phrases: R22-35, S26-36/37/39-45. When working with chemicals, always wear a suitable lab coat, disposable gloves, and protective goggles. For more information, consult the SDS sheets. CAUTION BeadChips are glass. Inspect for broken edges and handle with care. Infinium Karyomapping Assay Protocol Guide 7 Lab Setup and Maintenance Preventing Amplification Product Contamination The karyomapping assay protocol uses 2 whole genome amplification (WGA) processes, the first amplifies DNA from single or few cells to quantities suitable for the Infinium protocol (WGA1). The second is the first step of the Infinium protocol (WGA2). Unless sufficient caution is exercised, amplification products can contaminate reagents, instrumentation, and DNA samples, causing inaccurate and unreliable results. Amplification product contamination can shut down lab processes and significantly delay resumption of normal operations. For this reason, Illumina strongly encourages performing the amplification processes in separate, dedicated laboratory spaces. CAUTION It is imperative to establish procedures for preventing amplification product contamination before working in the lab. Separate WGA1, WGA2, and Post-Amp Areas The first whole genome amplification uses the SureMDA kit to amplify DNA from embryo biopsies, which are single cells (blastomere - day 3) or a few cells (5-10 cells, trophectoderm - day 5) taken from the developing embryo. The preparation for this amplification is included in the Amplification of biopsy samples with SureMDA section and is performed in the WGA1 area. DNA is amplified to quantities sufficient for use in the Infinium protocol. It is critical that this step is performed in a clean area, ideally in a clean 'sample protection' hood. The second amplification - WGA2 - is the first step of the Infinium protocol. The preparation for this amplification is included in the Prepare and Incubate the MSA3 plate section. Ideally WGA2 is performed in a physically separate laboratory area from the WGA1 area. Perform the remaining Infinium protocol in a post-amp area that is a separate laboratory space from the amplification areas. The 3 laboratory areas are referred to as WGA1, WGA2, and post-amp. Dedicated Equipment and Supplies Dedicate separate sets of instruments (pipettes, centrifuge, Illumina Hybridization Oven, heat block, etc.) to the pre-amp and post-amp areas. Never share instruments between areas. Follow these rules to avoid contaminating the pre-amp area: } Never use the same sink to wash pre-amp and post-amp reservoirs. } Never share the water purification system for pre-amp and post-amp processes. } Store all supplies used in the karyomapping assay protocols in the pre-amp area and transfer to the post-amp area as needed. Items Falling to Floor The floor can be contaminated with amplification product transferred on the shoes of individuals coming from the post-amp area. Therefore, treat anything falling to the floor as if it were contaminated. Throw away disposable items that have fallen to the ground at the completion of the assay. Disposable items can include empty tubes, pipette tips, gloves, or lab coat hangers. During the assay, never touch any items that have fallen to the ground. 8 Part # 15052710 Rev.B Use a 0.5% sodium hypochlorite (10% bleach) solution to clean any lab surface that has contacted the contaminated item. Individuals handling anything that has fallen to the floor, disposable or not, must throw away their lab gloves and put on a new pair. Infinium Karyomapping Assay Protocol Guide 9 Preventing Amplification Product Immediately and thoroughly clean nondisposable items that have fallen to the ground, such as pipettes or important sample containers. Use a 0.5% sodium hypochlorite (10% bleach) solution to remove product contamination. Lab Setup and Maintenance Preparing and Storing Reagents To minimize errors in preparing user-supplied reagents each day, prepare large batches of 95% Formamide/1 mM EDTA. Then aliquot and store them as described in the following sections. It is important to keep a ‘first in, first out’ or FIFO system for reagents. Rotating the stock of the remaining reagents helps to avoid accidentally using expired reagents. Prepare Batches of 0.1N NaOH Prepare 0.1 N NaOH fresh on the day of use from a liquid 10 N NaOH stock. Alternatively, prepare it in large batches and aliquot it into 1 ml sealed tubes. These aliquots can be stored for up to 12 months at 2°C to 8°C and used in the protocol as needed. When you open an aliquot, use it on the same day that it was opened. Discard any reagent that is left at the completion of the assay. Prepare Batches of 95% Formamide/1 mM EDTA To minimize errors in preparing 95% formamide/1 mM EDTA, prepare it in large batches and aliquot it into sealed tubes. These aliquots can be stored up to 5 months at -25°C to -15°C and used in the protocol as needed. When you open an aliquot, use it on the same day that it was opened. Discard any reagent that is left at the completion of the assay. WARNING This protocol uses an aliphatic amide (formamide) that is a probable reproductive toxin. Personal injury can occur through inhalation, ingestion, skin contact, and eye contact. For more information, consult the safety data sheet for this assay at support.illumina.com/sds.ilmn. Dispose of containers and any unused contents in accordance with the governmental safety standards for your region. Prepare SureMDA reagents Buffer DLB and Buffer D2 can be prepared before performing the SureMDA protocol and stored in single use aliquots (see SureMDA buffer preparation on page 24). 10 Part # 15052710 Rev.B To optimize your data and minimize errors and waste, read and follow these best practices whenever performing the karyomapping assay protocols. General Laboratory Practice Perform the protocols described in this guide with care while wearing appropriate personal protective equipment, including laboratory coat, eye protection, and gloves. Sample Mishandling To reduce the risk of sample mishandling, it is important to witness and sign off critical steps when following the laboratory protocol. Preparation of SureMDA Controls Positive controls DNA controls must be prepared freshly on the day of use for each SureMDA reaction and used promptly to reduce the risk of sample loss by adhesion to the plastic tube. Nucleasefree ‘LoBind’ tubes can be used to reduce this effect. Allow sufficient time for complete resuspension when serially diluting the DNA. Do not vortex DNA solutions as vortexing can shear the DNA. Control DNAs must be stored and handled away from test samples to prevent contamination. For control preparation instructions, see Preparation of amplification reaction controls on page 24. Negative controls Two types of negative control are recommended: a sample collection negative control (buffer control, or BC) for each batch of cell isolations and an amplification reaction negative control (no-template control, or NTC) per batch of amplification reactions. Illumina recommends that amplification reactions are performed in this way to make sure that no contamination of these solutions has occurred. As a result, the amplification products seen are a result of the single cells only. Cleaning and Calibrating Pipettes Make sure that pipettes are properly calibrated, clean, and decontaminated. Pipette Carefully Perform all pipette dispenses carefully and slowly to avoid creating turbulence within the plate wells and flow-through chambers. Where possible, use a multichannel pipette to dispense reagents. Handling Cap Mats Orient the cap mat so that A1 on the cap matches A1 on the plate. Infinium Karyomapping Assay Protocol Guide 11 Best Practices Best Practices Lab Setup and Maintenance CAUTION To prevent evaporation and spills, which could lead to assay variability and cross-contamination, make sure that all 96 caps are securely seated in the wells. When you remove a cap mat, do so carefully and slowly to avoid splashing the contents. Set the cap mat aside, upside down, in a safe location for use later in the protocol. When you place the cap mat back on the plate, be sure to match it to its original plate and orient it correctly. Reagent Reuse Never reuse excess reagents after dispensing. Discard according to your facility requirements. Handling BeadChips Avoid touching the BeadChip anywhere other than at the barcode end or on the edges. Balancing the Centrifuge Whenever you centrifuge plates or BeadChips, place a balance plate or rack with BeadChips opposite each plate or BeadChip rack being centrifuged. Make sure that weights are as similar as possible. 12 Part # 15052710 Rev.B Perform the following standard lab maintenance procedures for Infinium Assay labs. Daily and Weekly Bleaching CAUTION To prevent sample or reagent degradation, make sure that all bleach vapors have fully dissipated before starting any processes. Post-amplification Area Reducing the amount of product in the post-amp area reduces the risk of contamination in the pre-amp areas (WGA1 and WGA2). Identify post-amp area “hot spots” that pose the highest risk of contamination, and clean these items daily with a 10% bleach solution. Typical • • • • • • • • hot spots include: Bench space used to process amplified DNA Door handles Refrigerator/freezer door handles Computer mouse Keyboards Centrifuges Vortexers Thermal cyclers Every week, thoroughly bleach the entire post-amp area, including benchtops and instruments that are not cleaned daily. Mop the floors with a 0.5% sodium hypochlorite (10% bleach) solution as well. Provide training for personnel responsible for cleaning the lab areas so that they know how to prevent pre-amp product contamination. Pre-amplification Area Establish a daily and weekly bleaching schedule for the pre-amp areas (WGA1 and WGA2) similar to the schedule for the post-amp area. Bleaching helps to eliminate product that could have entered the pre-amp area. Identify high-risk pre-amp items such as the items listed, and clean them with a 0.5% sodium hypochlorite (10% bleach) solution each morning before beginning any pre-amp processes: • Benchtops • Door handles • Refrigerator/freezer door handles • Computer mouse • Keyboards Every week, thoroughly clean all laboratory surfaces and instruments, including all the benchtops and instruments that are not cleaned daily. Mop the floors with a 0.5% sodium hypochlorite (10% bleach) solution as well. Provide training for personnel responsible for cleaning the lab areas so that they know how to prevent pre-amp product contamination. Infinium Karyomapping Assay Protocol Guide 13 Lab Maintenance Lab Maintenance Lab Setup and Maintenance Cleaning the Glass Back Plates The glass back plates are used in the flow-through chambers to control the flow of sample and reagent onto the BeadChips. Clean the glass back plates when you open them for the first time and between uses. In addition, perform a more thorough cleaning after every 7 uses or weekly (depending on the throughput of your lab). Both procedures are described in the following sections. Cleaning the Glass Back Plates after Every Use When you open the glass back plates for the first time, and after every use, follow these instructions to clean them. 1 Prepare a 1% dilution (2.5 g per 250 ml) of Alconox Powder Detergent in water. 2 Dip each glass back plate into the solution. 3 Remove the glass back plates from the detergent solution and wipe them with a Kimwipe. 4 Hold the glass back plates under running DI water to remove any remaining detergent completely. 5 Allow the glass back plates to dry in the storage rack or by leaning the glass back plates at an angle against the black metal frames. 6 When the glass back plates are clean and dry, use a Kimwipe to wash with 70% EtOH. 7 Dry the glass back plates with a Whoosh duster or laboratory air gun. 8 To prevent surface damage to the glass back plates, store them in the Te-Flow Flow Cell storage box. Cleaning the Glass Back Plates Weekly In addition to the cleaning procedure in the previous section, clean the plates periodically after approximately every 7 uses and/or every week depending on individual lab throughput. CAUTION Wear a lab coat, safety goggles, and gloves during this cleaning process.

Steps to Wash BeadChip 1 Attach the wire handle to the rack and submerge the wash rack in the first wash dish containing 200 ml PB1. Figure 22 Wash Rack in Wash Dish Containing PB1 48 Part # 15052710 Rev.B Remove a BeadChip from the Hyb Chamber and then remove its cover seal. RELATED TRAINING To learn more, see the Removing the IntelliHyb Seal topic in the Infinium, Lesson 2: Assay Techniques training video on the Array Online Training page of the Illumina website. NOTE To make sure that no solution splatters on you, Illumina recommends removing the cover seal over an absorbent cloth or paper towels, preferably in a hood. CAUTION Inspect BeadChips for broken edges and handle with care. a b Using powder-free gloved hands, hold the BeadChip securely and by the edges in one hand. Avoid contact with the sample inlets. Make sure that he barcode is facing up and is closest to you, and that the top side of the BeadChip is angled slightly away from you. Remove the entire seal in a single, continuous motion. Start with a corner on the barcode end and pull with a continuous upward motion away from you and towards the opposite corner on the top side of the BeadChip. Figure 23 Removing the Cover Seal c Discard the cover seal. CAUTION Do not touch the arrays! 3 Immediately and carefully slide the BeadChip into the wash rack, making sure that the BeadChip is submerged in the PB1. Figure 24 Submerging BeadChips in Wash Dish Containing PB1 Infinium Karyomapping Assay Protocol Guide 49 Wash the BeadChip 2 karyomapping assay Protocol 4 Repeat steps 2 and 3 if necessary until all BeadChips are transferred to the submerged wash rack. 5 When all the BeadChips are in the wash rack, move the wash rack up and down for 1 minute, breaking the surface of the PB1 with gentle, slow agitation. 6 Move the wash rack to the other wash dish containing clean PB1. Make sure the BeadChips are submerged. 7 Move the wash rack up and down for 1 minute, breaking the surface of the PB1 with gentle, slow agitation. 8 When you remove the BeadChips from the wash rack, inspect them for remaining residue. NOTE Residue that can adversely affect results is sometimes left on BeadChips after seals are removed. If there is residue left on the BeadChips after the second PB1 wash, use a 200 μl pipette tip for each BeadChip. Slowly and carefully scrape off the residues outward (away) from the bead-sections under PB1. Use a new pipette tip for each BeadChip. Then, continue with the protocol. Assemble Flow-Through Chambers RELATED TRAINING To learn more about and assembling the flow-through chambers, see the flow-through chamber topic in the Infinium, Lesson 2: Assay Techniques training video on the Array Online Training page of the Illumina website. 1 If you have not done so, fill the BeadChip Alignment Fixture with 150 ml PB1. 2 For each BeadChip to be processed, place a black frame into the BeadChip Alignment Fixture.

Wash and Coat BeadChips Before starting the Wash and Coat process, read these important notes: } Take the utmost care to minimize the chance of lint or dust entering the wash dishes, which could transfer to the BeadChips. Place wash dish covers on wash dishes when stored or not in use. Clean wash dishes with low-pressure air to remove particulates before use. } Place a clean tube rack on top of several layers of Kimwipes or on an absorbent pad. You will place the staining rack containing BeadChips on this tube rack after removing it from the XC4 wash dish. } Prepare an additional clean tube rack that fits the internal dimensions of vacuum desiccator for removal of the BeadChips. Allow one rack per 8 BeadChips. No Kimwipes are required under this tube rack. } Wash the tube racks and wash dishes thoroughly after use. Rinse with DI water. Immediately following wash, place racks and wash dishes upside down on a wash rack to dry. Equipment Needed Place the following items on the bench: } 1 staining rack and wash dishes } 1 vacuum desiccator } 1 tube rack } Self-locking tweezers } Large Kimwipes } Vacuum hose Infinium Karyomapping Assay Protocol Guide 59 Extend and Stain (XStain) BeadChips 4 karyomapping assay Protocol Steps 1 Set up 2 top-loading wash dishes, labeled "PB1" and "XC4". 2 To indicate the fill volume before filling wash dishes with PB1 and XC4, pour 310 ml water into the wash dishes and mark the water level on the side. Empty the water from the wash dish. This enables you to pour reagent directly from the PB1 and XC4 bottles into the wash dishes, minimizing contaminant transfer from labware to wash dishes. Figure 37 PB1 and XC4 Wash Dishes with Staining Rack A B Wash Dishes Staining Rack 3 Pour 310 ml PB1 into the wash dish labeled “PB1.” 4 Submerge the unloaded staining rack into the wash dish with the locking arms and tab facing towards you. This orients the staining rack so that you can safely remove the BeadChips. Let the staining rack sit in the wash dish. You will use it to carry the BeadChips after disassembling the flow-through chambers. Figure 38 Staining Rack Locking Arms and Tab A 60 Locking Arms Part # 15052710 Rev.B 5 Tab One at a time, disassemble each flow-through chamber: a Use the dismantling tool to remove the 2 metal clamps. CAUTION It is important to use the dismantling tool to avoid chipping the glass back plates. Figure 39 Removing the Metal Clamps from Flow-Through Chamber b Remove the glass back plate by lifting the glass straight up. CAUTION Do not slide the glass along the BeadChip. This can damage the BeadChip. c d Set the glass back plate aside. When you finish the XStain protocol, clean the glass back plates. See Cleaning the Glass Back Plates on page 14 for instructions. Remove the spacer. To avoid damaging the stripes on the BeadChip, pull the spacer out so that the long sides slide along the sides of the BeadChip. CAUTION Do not remove the spacer before removing the glass. This can cause the glass and BeadChip to come into contact and can damage the BeadChip. e Remove the BeadChip from the black frame. CAUTION Do not touch the face of the BeadChips. Handle them by the barcode end or by the edges. 6 Place the BeadChips in the staining rack while it is submerged in PB1. Make sure that the BeadChip barcodes are facing away from you and that the locking arms on the handle are facing towards you. If necessary, briefly lift the staining rack out of the wash dish to seat the BeadChip. Replace it immediately after inserting each BeadChip. 7 Make sure that the BeadChips are submerged. CAUTION Do not allow the BeadChips to dry. Submerge each BeadChip in the wash dish as soon as possible. 8 Slowly move the staining rack up and down 10 times, breaking the surface of the reagent. NOTE If the top edges of the BeadChips begin to touch during either PB1 or XC4 washes, gently move the staining rack back and forth to separate the slides. It is important for the solution to circulate freely between all BeadChips. Infinium Karyomapping Assay Protocol Guide 61 Extend and Stain (XStain) BeadChips B karyomapping assay Protocol Figure 40 Washing BeadChips in PB1 9 Soak for 5 minutes. 10 Shake the XC4 bottle vigorously to ensure complete resuspension. If necessary, vortex until dissolved. 11 Pour 310 ml XC4 into the dish labeled “XC4,” and cover the dish to prevent any lint or dust from falling into the solution. CAUTION Do not let the XC4 sit for longer than 10 minutes. 12 Remove the staining rack from the PB1 dish and place it directly into the wash dish containing XC4. Figure 41 Moving BeadChips from PB1 to XC4 13 Slowly move the staining rack up and down 10 times, breaking the surface of the reagent. NOTE If the top edges of the BeadChips begin to touch during either PB1 or XC4 washes, gently move the staining rack back and forth to separate the slides. It is important for the solution to circulate freely between all BeadChips. 14 Soak for 5 minutes. 15 Remove the staining rack in one smooth, rapid motion and place it directly on the prepared tube rack. 62 Part # 15052710 Rev.B To ensure uniform coating, place the staining rack on the center of the tube rack, avoiding the raised edges. Figure 43 Staining Rack in Correct Orientation 16 For each of the BeadChips, working top to bottom: a Continuing to hold the staining rack handle, carefully grip each BeadChip at its barcode end with self-locking tweezers. NOTE The XC4 coat is slippery and makes the BeadChips difficult to hold. The selflocking tweezers grip the BeadChip firmly and help prevent damage. b Place each BeadChip on a tube rack with the barcode facing up and towards you. Infinium Karyomapping Assay Protocol Guide 63 Extend and Stain (XStain) BeadChips Figure 42 Moving the Staining Rack from XC4 to Tube Rack karyomapping assay Protocol Figure 44 BeadChips on Tube Rack TIP Remove the staining rack handle if it facilitates removal of the BeadChips from the staining rack. Holding the top of the staining rack in position, gently remove the staining rack handle by grasping the handle between the thumb and forefinger. Push up the tab with your thumb and push the handle away from you (unlocking the handle), then pull up the handle and remove. CAUTION To prevent wicking and uneven drying, do not allow the BeadChips to rest on the edge of the tube rack or to touch each other while drying. Do not use the bottom level of the tube rack. The back of the BeadChips will not dry as effectively and dye protectant could pool. 17 Place the tube rack in the vacuum desiccator. Each desiccator can hold 1 tube rack (8 BeadChips). CAUTION Make sure that the vacuum valve is seated tightly and securely. 18 Remove the red plug from the three-way valve before applying vacuum pressure. 19 Start the vacuum, using at least 675 mm Hg (0.9 bar). 20 To make sure that the desiccator is properly sealed, gently lift the lid of the vacuum desiccator. Make sure that the lid does not lift off the desiccator base. 21 Dry under vacuum for 50–55 minutes. Drying times can vary according to room temperature and humidity. 22 Release the vacuum by turning the handle slowly. WARNING Make sure that air enters the desiccator slowly to avoid disturbing the contents. Improper use of the vacuum desiccator can result in damage to the BeadChips. This is especially true if you remove the valve plug while a vacuum is applied. For detailed vacuum desiccator instructions, see the documentation included with the desiccator. 23 Store the desiccator with the red valve plug in the three-way valve of the desiccator to stop accumulation of dust and lint within the valve port. 24 Touch the borders of the chips (do not touch the stripes) to make sure that the etched, barcoded sides of the BeadChips are dry to the touch. 64 Part # 15052710 Rev.B CAUTION Do not touch the stripes with the wipe or allow EtOH to drip onto the stripes. 26 Perform 1 of the following: • Proceed to Scan the BeadChip. • Store the BeadChips in the Illumina BeadChip Slide Storage Box at room temperature. Scan the BeadChips within 72 hours. 27 Clean the glass back plates. See Cleaning the Glass Back Plates on page 14 for instructions. 28 Discard unused reagents in accordance with facility standards. Infinium Karyomapping Assay Protocol Guide 65 Extend and Stain (XStain) BeadChips 25 If the underside feels tacky, manually clean the underside of the BeadChip to remove any excess XC4 using a Kimwipe sprayed with 70% EtOH. The bottom 2 BeadChips are most likely to have some excess. a Hold the BeadChip at a downward angle to prevent excess EtOH from dripping from the wipe onto the stripes. b Wipe along the underside of the BeadChip 5 or 6times, until excess XC4 is removed. karyomapping assay Protocol Scan BeadChip Scan BeadChips using either the iScan system or the NextSeq 550 system. To perform a scan, you need Decode Map (DMAP) files, a manifest file, and a cluster file for the BeadChip you are using. } Use the Decode File Client to download the required DMAP folder. DMAP folders are unique for each BeadChip type. For more information, see the DMAP Decode File Client User Guide (part # 11337856). } Download the manifest and cluster files from the Illumina support website. Each manifest and cluster file is unique for each BeadChip type. If you are using the NextSeq 550 system, make sure to use files that include NS550 in the file name. } Scan your BeadChip using the iScan or the NextSeq system. For more information, see the iScan System User Guide (part # 11313539) or the NextSeq 550 System User Guide (part # 15069765). In the lab tracking form, record the Scanner ID and scan date for each BeadChip. } Output files are generated during the scan and then queued for transfer to the specified output folder. Perform analysis using BlueFuse Multi software, which requires that scanning data are available in a genotype call (GTC) file format. By default, the NextSeq 550 system generates normalized data and associated genotype calls in the format of a GTC file. The iScan can be configured to produce GTC files, in addition to the standard file types (such as IDAT files). Alternatively, you can use the Illumina Beeline software to convert IDAT files to GTC files after scanning. For more information, see Beeline Software User Guide (part # 15016340). 66 Part # 15052710 Rev.B This is a detailed protocol of how to prepare and carry out an agarose gel electrophoresis to resolve the amplified DNA products following the SureMDA protocol.

Making agarose gel solution and preparing gel mold 30 minutes 15 minutes 2. Loading samples into gel and running gel 30 min - 1 hour 5 minutes 3. Taking images and cleaning 10 minutes 10 minutes Procedure Steps Gel mold and comb preparation 1 Select the gel mold size suitable for the gel to be run. Common sizes available are 50 ml, 100 ml, 150 ml, and 400 ml. 2 Using autoclave tape, carefully tape the ends of the mold. If necessary, make sure that there are no gaps for the solution to leak through. 3 Select the correct sized comb for the gel mold and place into position. 4 Place the agarose mold on a flat horizontal surface. Preparation of agarose gel solution 1 Weigh out agarose powder and measure the required amount of 1xTBE buffer required for the gel. (e.g 0.8% agarose gel – 0.8 g agarose powder in 100 ml of 1x TBE buffer) 2 Add the 1xTBE buffer to the ‘gel bench’ bottle followed by the agarose powder, swirl to mix, place the lid on loosely. 3 Heat the agarose and buffer in the microwave for 1–2 mins, watching the solution to make sure that it does not bubble over. Remove using heat proof gloves and swirl to mix 2–3x during the 1–2 minutes. Heat until there are large bubbles arising to the surface. Make sure that solution is homogeneous by swirling gently. 4 Using heat proof gloves remove the bottle from the microwave and place on the gel bench to allow cooling for ~10–15 minutes. Make sure that the solution is cool enough to touch. Swirl gently from time to time to prevent localized setting of gel. 5 When the solution is cooled, add the GelRed™ and gently swirl to mix. Add 5 μl GelRed to every 50 ml of agarose gel solution. 6 Gently pour the agarose solution into prepared gel mold, pouring slowly to avoid air bubbles. If air bubbles occur, use a pipette tip to remove/move to the side. Leave to set for 1 hour before using. Loading and running the gel 1 68 When the gel is set, remove the tape from the edges and place the mold into the gel tank containing enough 1x TBE running buffer to cover the gel. Carefully remove the combs. Part # 15052710 Rev.B Make sure that the gel is placed in the correct orientation in the gel tank – DNA is negatively charged, so samples will migrate towards the positive electrode, which is typically red – run to red! 3 The gel is now ready for samples to be loaded into the gel wells. Prepare the samples by mixing 5 μl 2x loading buffer with 3 μl nuclease free water and 2 μl amplified DNA from the SureMDA protocol. Load the prepared samples slowly and carefully into the wells to avoid the samples floating out of wells. 4 Load 0.4 – 0.5 μg of a 0.05 μg/μl dilution of 1 kb DNA Extension Ladder either side of samples to enable size estimation of bands. Close lid of tank. Record which sample has been loaded into which well. 5 Connect the black and red leads to the black and red connections on the conductor (again ensure the correct orientation - run to red!). Set voltage to 120 V (or around 4V/cm) and run for 5 minutes (to check for product) then a further 35 minutes or 55 minutes to check for fragment length. 6 Check there is a current flowing by observing for bubbles arising from the electrodes at the bottom of the tank. Gel imaging (exact instructions will depend upon local setup) 1 Place the gel mold onto a sheet of paper towel, wipe the bottom of the mold dry, and place the gel directly on the UV transilluminator. Handle the tray with care as the gel can easily slip off. 2 On the live setting, position the mold so the samples are visible on the screen, zoom in/out as required. Close the door and turn on the UV source. 3 Adjust the focus settings to gain an ideal picture of your samples. 4 When happy with the image press the capture button on the UV transilluminator, then print or save the image. 5 Note any weak or failed reactions, contaminated negative controls, and any products that do not resemble the positive control.
