Carboxypeptidase A1 Antibody / CPA1 Pancreatic Acinar Cell Marker Antibody [clone CPA1/8163R] (V5257)

Carboxypeptidase A1 Antibody Tissue Panel WB. Western blot analysis of Carboxypeptidase A1 / CPA1 across human tissue lysates including brain, heart, intestine, kidney, liver, lung, ovary, pancreas, prostate, skeletal muscle, skin, spleen, stomach, and testis using rabbit monoclonal Carboxypeptidase A1 antibody, clone CPA1/8163R. A distinct band is detected at approximately 45 kDa exclusively in the pancreas lane, consistent with the predicted molecular weight of CPA1, demonstrating its highly restricted expression and supporting its use as a pancreatic acinar cell marker in tissue analysis.

Carboxypeptidase A1 Antibody Pancreas Multi-Species WB. Western blot analysis of Carboxypeptidase A1 / CPA1 across pancreas tissue lysates from human, mouse, rat, hamster, guinea pig, and rabbit using rabbit monoclonal Carboxypeptidase A1 antibody, clone CPA1/8163R. A band is detected at approximately 45 kDa in each species, consistent with the predicted molecular weight of CPA1, demonstrating conserved expression of this digestive enzyme and reinforcing its role as a pancreatic acinar cell marker across mammalian species.

Carboxypeptidase A1 Antibody Pancreas IHC. Immunohistochemistry of Carboxypeptidase A1 / CPA1 in FFPE human pancreas tissue using rabbit monoclonal Carboxypeptidase A1 antibody, clone CPA1/8163R. Strong HRP-DAB brown cytoplasmic staining highlights pancreatic acinar cells, consistent with the enzyme’s localization to secretory granules and supporting its use as a pancreatic acinar cell marker, while nuclei are counterstained blue. 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.
