The E.Z.N.A.® RNALock Stabilizer Reagent is an innovative reagent which rapidly lyses cells and tissues to inactivate RNases at room temperature. Simply submerge the samples, such as cell cultures, animal tissues, or white blood cells into the RNALock Stabilizer Reagent. The intact cellular RNA will be preserved even at elevated temperature. Samples can be stored in this reagent in excess of 12 months at −20°C.
