StayRNA™ is an aqueous, non-toxic tissue storage reagent that rapidly permeates tissues to stabilize and protect cellular RNA in situ in unfrozen specimens.
Tissue pieces are harvested and immediately submerged in StayRNA™ for storage without affecting the quality and quantity of RNA.
Thereby StayRNA™ eliminates the need to immediately process tissue specimens or to freeze samples in liquid nitrogen for later processing.
StayRNA™ stabilizes and protects RNA samples:
- 24 hours at 37 °C
- 1 week at 25 °C
- 1 month at temp. from +2 °C to +8 °C
- long-term storage at -20 °C or -80 °C
StayRNA™ has been tested on several tissues:
- vertebrate species, including brain, heart, kidney, spleen, liver, testis, skeletal muscle, fat, lung and thymus
- E. coli cells
- tissue culture cells
- white blood cells
- some plant tissues
