Anti-CPXM2 antibodies are used in the immunodetection of the protein carboxypeptidase X, M14 family member 2. In humans, the canonical protein has a reported length of 756 amino acid residues and a mass of 85.9 kDa. It has been described to be a secreted protein. A member of the Peptidase M14 protein family, CPXM2 is suspected to be involved in cell-cell interactions. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include 4632435C11Rik, carboxypeptidase Hlo, carboxypeptidase X (M14 family), member 2, carboxypeptidase-like protein X2, cytosolic carboxypeptidase, and inactive carboxypeptidase-like protein X2. CPXM2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. ELISA, Western Blot, and Immunohistochemistry are common applications for CPXM2 antibodies.
