M. Kuwada et al., A simplified procedure for purification of cytochrome P-450 by preparativeAmpholine gel for isoelectric focusing, PREP BIOC B, 30(2), 2000, pp. 125-132
The purification process for cytochrome P-450 is very complicated, involvin
g five or more column chromatography steps for the final preparation. This
paper describes a reduction in the number of the steps; it can be easily pu
rified from pig testis microsomes with improved the yield. As the first ste
p, DEAE-Toyopearl column chromatography is performed only once and then, as
the second step, the partially purified cytochrome P-450 is completely pur
ified by a preparative Ampholine FAG-plate Gel for Isoelectric Focusing. Th
e combination reduced the purification to a two-step procedure.
