The Tempus Blood RNA Tube can be used to stabilize and isolate total RNA from whole blood for gene expression analysis. Advantages of the Tempus Blood RNA Tube:

• Immediate one-step lysis of whole blood cells and stabilization of RNA—no RBC lysis or proteinase K treatment required
• Frozen global gene expression profiles are stable for up to five days at room temperature; more than seven days at 4°C

How it works
Each Tempus Blood RNA Tube contains 6 mL of Stabilization Reagent. When blood (3 mL) is drawn into the tube and mixed with the reagent, lysis occurs almost immediately. The Stabilization Reagent inactivates cellular RNases and selectively precipitates RNA; while genomic DNA (gDNA) and proteins remain in solution. Blood drawn into the Tempus Blood RNA Tube is stable for up to five days at room temperature or for at least seven days at 4°C.

Ancillary Products
When the Tempus Blood RNA Tube is used with the Tempus Centrifugal RNA Isolation Kit (Cat. No. 4380204), the resulting RNA is more stable and has a higher RNA yield.
