Anti-CSAG3A antibodies enable researchers to detect and measure the CSAG3A antigen in biological samples. This target is a reported synonym of the CSAG3 gene, which encodes CSAG family member 3. This protein is known to function in the response to xenobiotic compounds, among other biological roles. The human version of CSAG3A has a canonical amino acid length of 127 residues and a protein mass of 14.4 kilodaltons, although 3 isoforms have been identified.
