Preparation of protein extracts from Schizosaccharomyces pombe using trichloroacetic acid precipitation.

Abstract

Schizosaccharomyces pombe is an attractive model organism with which to study core principles of conserved molecular cell biology processes. The ability to monitor protein behavior following separation by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) underpins much of this activity. Here we describe a robust protocol for the preparation of protein samples for analysis by SDS-PAGE.
