Gene Expression & Genotyping

Blood Collection Devices for Ambient Preservation of Cellular DNA, RNA and Genomic DNA

Sensitive genetic material can rapidly alter in drawn blood, impacting a range of analyses and applications including transcript profiling, DNA methylation, and long-range PCR. While the clinical moniker “fresher is better” certainly applies, in many case, blood samples are drawn at remote locations and shipped to central laboratories or research facilities- a process where the shipment cycle alone is often longer than 24 hours and in other cases may average closer to 5 days (A). If not stabilized, RNA begins to degrade within 24 hours (B).
