Figure 4From: Functional and biochemical characterization of the 20S proteasome in a yeast temperature-sensitive mutant, rpt6-1Comparative subunit compositional analysis by one-dimensional electrophoresis. (A) Purified 20S proteasomes were subjected to nondenaturing-PAGE in a 4% continuous polyacrylamide gel and (B) SDS-PAGE in a 12% polyacrylamide gel. The gels were stained with Coomassie Brilliant Blue R-250 and silver, respectively. The arrows indicate bands differing between strains.Back to article page
