We currently register and process approximately 25-30,000 samples a month through the team; this includes extracted and pre-extracted DNA and RNA. Samples will be processed using a laboratory information management system (LIMs) which provides unique Sanger IDs per sample as well as per container. Containers are also electronically stored using this ID in our growing freezer farm.
Samples are requested to be supplied in specific labware types as well as differing concentration/volume/total amounts depending on the destination pipeline team. This ensures that there is sufficient sample for QC and for successful downstream processing. The accepted labware types and requirements are available in our submission guidelines.
For DNA and RNA we use various processes to determine sample volume, sample concentration, RNA integrity number and a SNP genotyping assay in order to Quality Check samples in Sample management.
Currently Sample Management offer two types of Fluidigm chips capable of testing using three sets of assays as part of the standard human QC.
- 192.24 chip which utilises the 22 QC plex SNPs and 2 gender SNPs
- 96.96 DDD project chip which utilises 57 SNPs of which 22 are QC plex SNPs and 3 are gender SNPs
- 96.96 CGP project chip which utilises 95 SNPS of which 22 are QC plex SNPs and 3 are gender SNPs
Normalisation and Formatting:
Post QC Sample Management can normalise DNA/RNA samples in terms of concentration and volume using automated liquid handlers. Samples can also be re-arrayed according to their unique identifiers and downstream specifications.
Currently within Sample Management we have several automated extraction platforms capable of isolating DNA and/or RNA from differing input materials and labware types. These automated platforms include the Qiagen QIAcube and QIAsymphony. We also have semi-automated processes and can carry out more bespoke extractions if required.
Sample Management can extract from various fresh or frozen sample types including: Cell pellets, Tissue, Blood, Buffy Coat, Saliva, virus/pathogens, dried blood spots and saliva on FTA cards. Samples can be sent in pre-lysed or lysed in house on request.
We have a containment level 2 lab within our current facility allowing us to receive hazard group one and two biological agents For any queries, please contact Sample Management for an extraction project proposal form or our submission guidelines.
