Anti-Trypsin-3 Antibody

Trypsin-3 (PRSS3) is a calcium-dependent serine protease of the trypsin family that is expressed primarily in pancreatic acinar cells, with lower levels also reported in brain and select epithelial tissues. This unconjugated polyclonal reagent from Antibodies.com is raised in rabbit and is suitable for researchers probing PRSS3 expression by Western blot and immunohistochemistry on human samples. Supplied as 100 µg of affinity-purified antibody in a vial, it supports detection of the catalytically active zymogen and processed forms in tissue sections and cell lysates, applicable to studies of pancreatic exocrine function, pancreatitis models, and tumor biology contexts in which PRSS3 dysregulation has been reported. The unconjugated format allows flexibility in choosing secondary reporters, including HRP-, biotin-, or fluorophore-conjugated systems, depending on the in vitro detection method. For long-term storage, the vial should be kept refrigerated; aliquoting upon first use helps minimize freeze-thaw degradation across repeated experimental cycles.
