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

The above data are indicative only. When selecting the storage conditions for samples, the lowest possible / achievable temperatures and the shortest possible storage times at temperatures above -20 °C should always be used.

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
  • Drosophila
  • tissue culture cells
  • white blood cells
  • some plant tissues
