Anti-MDR2 antibodies are protein reagents that detect specific antigens. The MDR2 antigen is another term for the human protein ATP binding cassette subfamily B member 4, encoded by the ABCB4 gene. The protein is known to function in the metabolism of lipids, among other biological roles. Canonically, it has an amino acid length of 1286 residues and a mass of 141.5 kilodaltons. Its subcellular localization is in the cell membrane, cytoplasmic vesicles, and cytoplasm and it is expressed in the liver. The MDR2 protein is a member of the ABCB protein family. Other alias names for MDR2 include ABC21, GBD1, and ICP3. Western Blot is the most common application for the MDR2 antibodies listed below. ELISA, Immunocytochemistry, and Immunohistochemistry are also common applications.
