General description

Ribonucleic Acid (RNA) from baker’s yeast (S. cerevisiae) is the substrate for RNase enzyme. The isolation of RNA from yeast is a complicated process and involves heating and freezing cycles of cells in the presence of phenyl and detergents (SDS).

Application

Ribonucleic Acid (RNA) from baker’s yeast (S. cerevisiae) is suitable for applications such as northern blot hybridization, reverse transcriptase-polymerase chain reaction (RTPCR), and cDNA construction.

Preparation Note

Prepared by a modification of Crestfield, A.M., et al., J. Biol. Chem., 216, 185 (1955).
