Carboxypeptidase A1 Antibody / CPA1 [clone CPA1/9622R] (V5487)

Carboxypeptidase A1 Antibody Multi-Species Pancreas WB. Western blot analysis of Carboxypeptidase A1 / CPA1 across multiple species pancreas tissue lysates using rabbit monoclonal Carboxypeptidase A1 antibody, clone CPA1/9622R. Lanes show human pancreas, mouse pancreas, rat pancreas, hamster pancreas, guinea pig pancreas, and rabbit pancreas. A band is detected at approximately 45 kDa in each species, consistent with the predicted molecular weight of CPA1, demonstrating conserved expression of this pancreatic digestive enzyme across mammalian species.

Carboxypeptidase A1 Antibody Pancreas WB. Western blot analysis of Carboxypeptidase A1 / CPA1 in human pancreas tissue lysate using rabbit monoclonal Carboxypeptidase A1 antibody, clone CPA1/9622R. A band is detected at approximately 45 kDa, consistent with the predicted molecular weight of CPA1, reflecting its expression as a digestive enzyme produced by pancreatic acinar cells.

Carboxypeptidase A1 Antibody Pancreas IHC. Immunohistochemistry of Carboxypeptidase A1 / CPA1 in FFPE human pancreas tissue using recombinant rabbit monoclonal Carboxypeptidase A1 antibody, clone CPA1/9622R. Strong HRP-DAB brown cytoplasmic staining highlights pancreatic acinar cells, consistent with the enzyme’s role in digestive protein processing, while nuclei are counterstained blue. The staining pattern shows robust and uniform labeling of acinar cell populations with minimal background signal. Inset: PBS was used in place of primary antibody as a negative control to confirm specificity of staining. Heat induced epitope retrieval was performed by boiling tissue sections in pH 9 10 mM Tris with 1 mM EDTA for 20 min followed by cooling prior to staining.
