Anti-CD243 antibodies enable researchers to detect and measure the CD243 antigen in biological samples. This target is a reported synonym of the ABCB1 gene, which encodes ATP binding cassette subfamily B member 1. This protein is known to function in the metabolism of lipids and the response to xenobiotic compounds, among other biological roles. The human version of CD243 has a canonical amino acid length of 1280 residues and a protein mass of 141.5 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane and cytoplasm of cells and notably expressed in the liver, gallbladder, cerebral cortex, and adrenal gland. Other names for this target antigen include ABC20 and CLCS. A number of CD243 antibodies have been mentioned in research publications and have associated citations. Western Blot and Immunohistochemistry are common applications for these antibodies.
