ABSTRACT:
Shelf-stable solvent solutions and methods for simultaneously isolating RNA, DNA and proteins from biological samples are disclosed. The solvent solutions include phenol and a guanidinium compound, preferably at a concentration below about 2M, which is effective in isolating substantially pure and undegraded RNA, substantially pure and undegraded DNA, and proteins from the same biological sample.
