To avoid sample breakdown and allow for the most accurate analysis and profiling results, a stabilization reagent should be added to the blood samples prior to RNA purification. This also allows for long term storage of samples.

To minimize the high ribonuclease (RNase) activity in blood plasma, we offer two options: 1) blood samples can be drawn directly into Tempus™ Blood RNA Tubes, which contain a stabilizing reagent, 2) addition of RNAlater® Stabilization Solution immediately after blood sample collection.”
