Immunoprecipitation of CPA2 transfected lysate using anti-CPA2 MaxPab rabbit polyclonal antibody and Protein A Magnetic Bead (U0007), and immunoblotted with CPA2 purified MaxPab mouse polyclonal antibody (B01P) (H00001358-B01P).
Three different forms of human pancreatic procarboxypeptidase A have been isolated. The encoded protein represents the A2 form, which is a monomeric protein with different biochemical properties from the A1 and A3 forms. The A2 form of pancreatic procarboxypeptidase acts on aromatic C-terminal residues and is a secreted protein. [provided by RefSeq
