Anti-CT45A3 antibodies are used in the immunodetection of the protein cancer/testis antigen family 45 member A3. In humans, the canonical protein has a reported length of 189 amino acid residues and a mass of 21.3 kDa. It is reported to have testis-specific expression. It is a member of the CT45 protein family. Synonyms for this target antigen include cancer/testis antigen 45-3, cancer/testis antigen 45-4, cancer/testis antigen 45A3, cancer/testis antigen 45A4, and cancer/testis antigen family 45 member A3. Western Blot is the most common application for the CT45A3 antibodies listed below. Immunocytochemistry and Immunohistochemistry are also common applications.
