Anti-SPINT2 Antibody

SPINT2 (Serine Peptidase Inhibitor, Kunitz Type 2), also known as HAI-2, is a membrane-associated serine protease inhibitor that regulates activation of hepatocyte growth factor (HGF) and matriptase, with documented roles in epithelial sodium transport, intestinal barrier function, and tumor suppression in hepatocellular and gastric carcinomas. This unconjugated rabbit polyclonal primary antibody from Antibodies.com targets human SPINT2 and has been validated for Western blot, immunohistochemistry, and immunofluorescence workflows.

Supplied as 100 µl of antibody at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, the reagent is ready to dilute into standard blocking and incubation buffers. Aliquot upon first thaw to limit freeze-thaw cycles, store at -20°C, and protect from light to preserve activity across experiments probing HGF/MET signaling, epithelial differentiation, or SPINT2 expression in tissue sections.
