Anti-CT103 antibodies are used in antigen-specific immunodetection in biological samples. The target CT103 is a known alias name of the protein semenogelin 1, encoded by the SEMG1 gene in humans. This 462-amino acid residue protein is a member of the Semenogelin protein family. The protein is secreted and features post-translational modifications. It is reported to be expressed in the seminal vesicle. The term SEMG is another synonym for CT103.
