Scientific Data Images for Human Trypsin 1/PRSS1 Antibody

Trypsin 1/PRSS1 antibody in Human Pancreas by Immunohistochemistry (IHC-P).

Trypsin 1/PRSS1 in Human Pancreas.

Trypsin 1/PRSS1 was detected in immersion fixed paraffin-embedded sections of human pancreas using Mouse Anti-Human Trypsin 1/PRSS1 Monoclonal Antibody (Catalog # MAB3848) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to exocrine cells.

Background: Trypsin 1/PRSS1

Human Trypsin 1, encoded by the PRSS1 gene, is also known as Cationic Trypsinogen (1). Constituting approximately two-thirds of the total trypsin content in normal pancreatic juice, it is the most abundant trypsin isoform produced by the pancreas. It contains a signal peptide (residues 1‑15), a pro region (residues 16‑23), and a mature chain (residues 24‑247). Trypsin 1 is synthesized in the pancreas and secreted into the duodenum lumen, where it is activated by enterokinase. Its major physiologic function is to digest food and to activate other pro-enzymes (2). Mutations in the PRSS1 gene can cause hereditary pancreatitis (3).
