Rapid protein extraction from Saccharomyces cerevisiae

Yeast. 1994 Oct;10(10):1305-10. doi: 10.1002/yea.320101007.

Abstract

We have developed and evaluated an easy and rapid method for extraction of proteins from yeast cells for sodium dodecyl sulphate (SDS)-gel electrophoresis and Western blotting. The procedure comprises a centrifugation step to harvest the cells, addition of a sample buffer and heating, then another centrifugation step before applying the extracted proteins found in the supernatant to an SDS gel. It is applicable to the study of large numbers of samples in 1 day. This procedure is easier, quicker, and as efficient as procedures using base and 2-mercaptoethanol, but somewhat less efficient than lysis with glass beads under certain conditions.
