Anti-SPINT1 Antibody

Manufactured by Antibodies.com, this rabbit polyclonal reagent targets serine peptidase inhibitor Kunitz type 1 (SPINT1), also known as HAI-1, a membrane-associated Kunitz-type serine protease inhibitor implicated in the regulation of cell-surface proteolysis and pericellular signaling. The antibody is supplied as 50 µl of an unconjugated, affinity-purified IgG preparation at 1.0 mg/mL in phosphate-buffered saline (pH 7.4) containing 150 mM NaCl, 0.02% sodium azide, and 50% glycerol as a cryoprotectant. It was raised against a recombinant human SPINT1 immunogen and detects endogenous levels of total SPINT1 protein. Validated applications include Western blotting (WB) and immunocytochemistry/immunofluorescence (ICC/IF), and the antibody has been tested for reactivity against Human, Mouse, and Rat samples, making it a versatile choice for cross-species studies. Short-term storage at 4 °C is acceptable, but for longer retention the product should be aliquoted and kept at –20 °C with freeze/thaw cycles avoided to preserve binding activity. The format is intended for research use only and is not cleared for diagnostic or therapeutic work. The host species, clonality, conjugate state, and validated assays listed on the supplier's product page align with the catalogue entry, giving laboratories a well-characterized tool for probing SPINT1 expression in cultured cells and tissue lysates.
