FAQ-3463
How long can the tubes be kept frozen at –20°C or –70°C?
Currently we have data for storage at –20°C and –70°C for 11 years.
Long term archiving studies are ongoing. See technical note: In Situ Stability of RNA in Blood Samples Stored at –20°C and –70°C in PAXgene Blood RNA Tubes.

PAXgene Blood RNA Kit (IVD)
The PAXgene Blood RNA System consists of a blood collection tube (PAXgene Blood RNA Tube) and a nucleic acid purification kit (PAXgene Blood RNA Kit). It is intended for the collection, storage and transport of blood and stabilization of intracellular RNA in a closed tube, and subsequent isolation and purification of host RNA from whole blood for RT-PCR used in molecular diagnostic testing.
Performance characteristics for the PAXgene Blood RNA System have only been established with FOS* and IL1B** gene transcripts. The user is responsible for establishing appropriate PAXgene Blood RNA System performance characteristics for other target transcripts.
*FOS is the gene symbol for human Fos Proto-Oncogene, AP-1 Transcription Factor Subunit.
**IL1B is the gene symbol for human Interleukin 1 Beta.
