MDL No.: MFCD02687283

Purity: >=90% (SDS-PAGE)

Storage: -70C

UNSPSC Code: 12161501

Biochem/physiol Actions: Cytochrome b5 is a membrane-bound heme-containing protein that enhances the catalytic efficiency of some P450 isoforms. Its mechanism of action is unknown.

Physical form: Solution in 20 mM phosphate buffer, pH 7.25, with 0.1 mM EDTA

Analysis Note: Heme content measured using difference spectroscopy. An extinction coefficient of 100 mM-1 for the absorbance difference between 490 nm and 424 nm is used to calculate the concentration of cytochrome b5.
