I am afraid that my RNA degrades. I have prepared about 1.5 months back and will send for sequencing in the first week of Jan. In total, about 2 months. I think it wont degrade but I am afraid..it is a precious sample and tough preparation.
I have not done snap frozen but I keep just after RNA preparation in -80 and checked bioanalyser when I was storing sample. since then I have not taken sample out and I will have to wait till 10th Jan as it is Christmas time.
and did you do transcriptomics with the stored sample or qPCR?
If you store with RNA storage solution from Thermo Scientific in -80 it will stable for 6-12 months but better to synthesize cDNA and store it in -20, because RNA has its own self life.
