RNAstay is ready-to-use, non-toxic tissue RNA storage reagent, which rapidly permeates tissue to stabilize and protect cellular RNA in situ in unfrozen specimens. RNAstay is compatible with most RNA isolation methods, including Trizol and Total RNA isolation and mammalian mRNA isolation kits.

Samples storage times:
18-25°C for 7days
4°C for one month
-20°C for 3~5 years
-80°C for long term storage

Store at Room Temperature for 1 year.
Store at 4℃ for 2 years.  If a precipitate develops in the RNAmaintain, warm the solution to 37 ℃ and agitate to redissolve it.
