Anti-CP8B antibodies enable researchers to detect and measure the CP8B antigen in biological samples. This target is a reported synonym of the CYP8B1 gene, which encodes cytochrome P450 family 8 subfamily B member 1. This protein is known to function in metabolic processes, among other biological roles. The human version of CP8B has a canonical amino acid length of 501 residues and a protein mass of 58.1 kilodaltons. It is reported to be localized in the ER of cells. Other names for this target antigen include CYP12 and 7-alpha-hydroxycholest-4-en-3-one 12-alpha-hydroxylase.
