Anti-cytochrome P450 2E1 antibodies enable researchers to detect and measure the cytochrome P450 2E1 antigen in biological samples. This target is a reported synonym of the CYP2E1 gene, which encodes cytochrome P450 family 2 subfamily E member 1. This protein is known to function in metabolic processes, among other biological roles. The human version of cytochrome P450 2E1 has a canonical amino acid length of 493 residues and a protein mass of 56.8 kilodaltons. It is reported to be localized in the mitochondria and ER of cells and notably expressed in the liver. Other names for this target antigen include CPE1, CYP2E, and P450-J. A number of cytochrome P450 2E1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
