1. Introduction
These guidelines have been drafted by the CPGR to ensure the following:
1.1. Chain of custody for samples and the authority to carry out testing is maintained
1.2. Testing is not delayed by the receipt of samples that do not meet the stringent quality
criteria required for high end omics projects.
1.3. No uncertainty of measurement is introduced by contaminants or additives that may
adversely affect the testing of samples.
The purpose of these guidelines is to ensure that testing and analysis is completed in the
shortest possible time, to the highest possible standards.
Samples that do not conform to the requirements of this guideline will not be accepted for
testing.
Queries can be directed to the platform manager or project manager dealing with your
project, or submitted to [email protected].
2. General Requirements
2.1. Samples must be submitted in clearly labeled tubes, preferably with a printed label
containing a barcode.
2.2. Samples must be accompanied by a shipping manifest. To maintain chain of custody,
two paper copies of the manifest must accompany the samples. The copies will be
signed and one copy returned as proof of delivery/acceptance. An electronic copy of
the manifest must be sent prior to delivery of the samples to [email protected]
2.3. The sample volume and sample concentration must be included.
2.4. Samples must be submitted in a cryobox and the position of the samples must be
indicated on the manifest. If you do not have a cryobox, the CPGR will provide one or
more at a fee.
2.5. Plastics such as cryovials, microtubes or plates can be purchased from the CPGR.
2.6. Samples must be submitted at the correct temperature.
2.7. The hazardous or infectious nature of samples must be indicated.

2.8. Samples that need to be handled in a BSL III or BSL IV Laboratory environment cannot
be accepted.
2.9. Samples containing radioactive substances cannot be accepted.
2.10. The following details must be provided:
2.10.1. Processing, isolation, extraction, or purification methods.
2.10.2. Any freeze thaw cycles.
2.10.3. Fate of the left over samples (destroyed, stored, returned).
2.10.4. Date and time of sample collection.
3. DNA
3.1. Samples may be submitted in 96 well plates (for 24+samples) or microtubes
3.2. The sample list and plate layout must be sent to the CPGR as an electronic manifest in
the CPGR’s template.
3.3. Initial QC data including gel electrophoresis carried out in your lab must be sent to
CPGR electronically. Submitted DNA must be of suitable integrity.
3.4. The DNA must meet the following criteria::
260/280 ratios between 1.8 – 2.1
260/230 ratios greater than 1.5
3.5. Visibly contaminated samples may not be included
3.6. Degraded or RNA contaminated samples may not be included
3.7. Samples must be transported on dry ice (Solid CO2)
3.8. The elution buffer must be clearly indicated and an aliquot included for CPGR QC
purposes
4. RNA
4.1. Samples may be submitted in 96 well plates (for 24+samples) or microtubes:
4.2. The sample list and plate layout must be sent to the CPGR as an electronic manifest in
the CPGR’s template. A copy of the template can be found here

4.3. Initial QCs including bioanalyser results carried out in your lab must be sent to CPGR
electronically. Submitted RNA must be of suitable integrity.
4.4. The RNA criteria to be met are:
260/280 ratios between 1.8 and 2.1:
260/230 ratios greater or equal to 1.5:
RIN Value greater than 7
4.5. Visibly contaminated samples may not be included
4.6. Samples must be transported on dry ice (Solid CO2)
4.7. Degraded or DNA contaminated samples may not be included
4.8. The elution buffer must be clearly indicated and an aliquot included for CPGR QC
purposes. N.B. RNA should not be eluted in DEPC treated water
5. Blood, blood products and tissue samples
5.1. Fresh whole blood samples must be submitted within 4 hours of collection for
processing.
5.2. Where blood has been stored in a stabilization reagent, please indicate details of the
stabilization reagent (e.g. RNAlater, Paxgene)
5.3. Cryopreserved samples must be submitted in polypropylene tubes or cryovials. Glass
vials will not be accepted. The correct cryoagent must be used for transport and
handling (vapour phase nitrogen (-160oC) ordry ice (-80oC, solid CO2)
5.4. Viable samples submitted in nitrogen must be stored in a cryovial containing an internal
threaded lid and a silicone gasket.
5.5. The following must be clearly indicated before samples are submitted:
5.5.1. Time and date of collection
5.5.2. Anticoagulant used in plasma samples such as EDTA, ACD, Na Citrate, Na Fl
etc
5.5.3. Fixatives such as formalin,
5.5.4. cryopreservatives such as glycerol or DMSO,

5.5.5. Detergents such as SDS
5.5.6. Denaturants, for example urea
5.6. To prevent unnecessary thawing of samples, serum samples should be aliquoted into
individual cryotubes. “PCR-strip” like tubes should never be used.
