Add 1X DNA/RNA Protection Reagent to sample. Solid tissue samples should be submerged in protection reagent, not to exceed 10% (w/v). For maximal RNA recovery, tissues can be mechanically homogenized using a bead mill or similar device. For every 300 µl of DNA/RNA Protection Reagent/sample mixture, add 30 µl Prot K Reaction Buffer + 15 µl ...

RNA remains exclusively in the aqueous phase (which is about 60% of the volume of TRIzol reagent used for initial homogenization). However, the organic phase can be saved for subsequent DNA and protein extraction. C. RNA Precipitation 1. Add 0.5 mL of isopropanol per 1 mL of TRIzol reagent originally used to a new tube. 2.
