Anti-CPA5 antibodies are used in the immunodetection of the protein carboxypeptidase A5. In humans, the canonical protein has a reported length of 436 amino acid residues and a mass of 49 kDa. It has been described to be a secreted protein. Up to 3 different isoforms have been reported for this protein. A member of the Peptidase M14 protein family, CPA5 is known to be involved with proteolysis. Synonyms for this target antigen include testicular tissue protein Li 32. CPA5 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Western Blot is a widely used application for the CPA5 antibodies listed below. In addition, ELISA is also a common application.
