β¦ Synopsis
NADH-cytochrome
b, reductase has been solubilized by extraction of rabbit liver microsomes with 1 M potassium phosphate buffer (pH 7.4), and has been purified to comparable purity with the Triton X-1OOsolubilized enzyme. Gel electrophoresis indicated an apparent molecular weight of 33,000 for both phosphate buffer-extracted and Triton X-100~solubilized enzymes. Phosphate buffer extraction provides a simple mild procedure for the extraction of NADH-cytochrome b, reductase that avoids detergents or proteolytic agents.
