Anti-HABP2 Antibody

HABP2 (Hyaluronan-Binding Protein 2), also termed Factor VII-activating protease (FSAP), is a circulating serine protease implicated in contact activation, extracellular matrix remodeling, and hyaluronan turnover. The Antibodies.com polyclonal reagent is raised in rabbit and supplied as an unconjugated whole IgG preparation at approximately 1 mg/ml in PBS with 15 mM sodium azide added as preservative. Each vial contains 50 µl of antibody; dilute into standard Western Blot workflows according to user-established protocols. The antibody is reactive with human and rat HABP2 by immunoblotting, enabling studies of coagulation biology, vascular pathology, and tumor microenvironment processes. Expected signal appears as a band near 64 kDa, corresponding to the mature single-chain protease subunit, with the heavy chain detectable under reducing conditions. The rabbit polyclonal format provides broad epitope coverage, useful when probing protein variants or splice isoforms, and the product is supplied as a single-use aliquot prepared for immediate loading on gels without additional purification steps.
