I actually extracted new samples of total rna from my tissues in the rnalater and compared them with the total rna that was at room temperature via rt.
Rna stability at room temperature.
The figures show biological samples stored in rna lock reagent can last up to 1 day at 30 37 c 6 days at room temperature 20 25 c and 1 month at 4 c conditions.
Stability of extracted rna.
Every week 5 spin columns that were preserved at room temperature were eluted with rnase free buffer according to manufacturer s guidelines and analyzed by real time quantitative rt pcr rrt qpcr to determine the ct value of preserved rna.
Room temperature storage 18 25 c in rnalater is possible for up to 7 days according to manufacturer s instructions although significant mrna degradation was detected after 3 days of room temperature storage of rat liver samples soaked in rnalater.
400 pinnacle way suite 450 norcross ga 30071.
Total rna purified after storing in the rna lock reagent.
If rna is in a stable buffer with rnase inhibitors it can even stay at room temperature for multiple days without much degradation.
For room temperature or 4 c storage oligos that are resuspended in te buffer 10 mm tris ph 8 0 0 1 mm edta.
The quality of rna preserved in different stabilization matrices was investigated after 2 weeks of storage at room temperature.
However at 4 c oligos stored under all of these conditions are stable for at least 60 weeks.
Rna stability and storage rna transport.
Such as idte are more stable than dry oligos.
Rna samples in rnastable biomatrica gentegra integenx and rnashell imagene were compared to rna stored at 80 c the current gold standard for rna preservation and with liquid or dried rna stored at room temperature without additives in this multi center.

Purified rna samples are handled minimally and kept cold at all times unless otherwise.
Baseline testing of 5 spin columns was performed and viral rna stability was evaluated periodically for 16 weeks.
