Trypsin 3/PRSS3 Antibody [Unconjugated]

Trypsin 3/PRSS3 was detected in perfusion fixed frozen sections of mouse pancreas using 5 µg/mL Goat Anti-Mouse Trypsin 3/PRSS3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3565) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Trypsin 3/PRSS3 was detected in perfusion fixed frozen sections of mouse pancreas using Mouse Trypsin 3/PRSS3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3565) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Lower panel shows a lack of labeling if primary antibodies are omitted and tissue is stained only with secondary antibody followed by incubation with detection reagents.

Background

Mouse Trypsin 3, encoded by the PRSS3 gene, is also known as mesotrypsin. It consists of a signal peptide (residues 1-15), a pro region (residues 16-23), and a mature chain (residues 24-246) (1). The purified recombinant mouse Trypsin 3 corresponds to the pro form, which can be activated by enterokinase.
