Anti-CT3.2 antibodies enable researchers to detect and measure the CT3.2 antigen in biological samples. This target is a reported synonym of the MAGEB2 gene, which encodes MAGE family member B2. This protein is known to function in the regulation of transcription, among other biological roles. The human version of CT3.2 has a canonical amino acid length of 319 residues and a protein mass of 35.3 kilodaltons. It is reported to be notably expressed in the testis.
