Rubins 2003 - Trizol Extraction of Total RNA from PBMCs; 1. Make sure the area is clean and free of any RNases. Keep the samples cold or on ice as much as possible to prevent RNA degradation. Use only RNase free tubes and RNase free, aerosol-barrier pipette tips throughout the whole experiment. 2. Add 1mL of Trizol to the frozen PBMC pellet. 3. If the Trizol was added to the PBMCs before freezing, thaw the Trizol/PBMCs on the benchtop for 5-10 minutes. 4. Vortex and transfer to 1.5ml microfuge tubes if not already in them. 5. Add 0.2 mls chloroform per 1 ml Trizol. Vortex or shake vigorously and incubate at room temp. for 2-3 minutes. 6. Centrifuge at 12,000g for 15 minutes at 4C. 7.
