      Recombinant, human cytochrome b5 expressed in E. coli. A membrane-bound hemoprotein that enhances the catalytic efficiency of some P450 isoforms, most notably members of the 3A subfamily. Serves as an electron buffer and is speculated to play either a direct role in electron transfer or an indirect role through allosteric interactions with P450. Suitable for in vitro drug metabolism and toxicology studies including reconstituted P450-dependent biotransformation reactions.
      Heme content: ≥60 nmol/mg protein.
