Anti-SERPINA3 Antibody

Raised in rabbit, this polyclonal primary antibody targets SERPINA3 (serpin family A member 3), a serine protease inhibitor also known as alpha-1-antichymotrypsin that functions as an acute-phase reactant primarily synthesized in hepatocytes. Supplied by Antibodies.com at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, the unconjugated reagent ships as a 100 µl vial suited to western blot and immunohistochemistry workflows on human samples. Polyclonal reactivity broadens epitope coverage across the serpin, supporting detection of full-length protein as well as disease-associated variants reported in hepatocellular carcinoma, pancreatic ductal adenocarcinoma, and neurodegenerative research on amyloid plaque pathology. The unconjugated format gives researchers flexibility to pair the antibody with HRP, biotin, or fluorophore-labelled secondary reagents of their choice, making it a practical tool for tissue-based biomarker studies, immunoblot validation experiments, and serum profiling in inflammatory disease research.
