Anti-SERPINA1 Antibody

Manufactured by Antibodies.com, this rabbit polyclonal reagent targets SERPINA1, the gene encoding alpha-1 antitrypsin, and is supplied as a 50 µl aliquot at a working concentration of 1 mg/ml in PBS supplemented with 0.1% sodium azide and 50% glycerol. The antibody is unconjugated, is affinity-purified to an estimated purity greater than 95%, and is raised in rabbit as a polyclonal preparation of the IgG isotype, intended for research use only. According to the supplier datasheet, its validated application is Western Blot, where it is expected to detect endogenous SERPINA1 across human, mouse and rat samples, making it a suitable reagent for comparative studies of serpin family expression in cell and tissue lysates. The unconjugated format allows researchers to couple the primary antibody to their preferred fluorophore, biotin or HRP for downstream detection in WB workflows, while the glycerol-containing buffer provides cryoprotection suitable for routine short-term storage at -20 °C and repeated freeze-thaw handling in laboratory settings. With reactivity confirmed for three commonly used mammalian model species, this lot offers flexibility for laboratories running parallel human and rodent expression panels, and the polyclonal nature of the reagent increases the likelihood of recognizing multiple epitopes on the SERPINA1 target for robust signal generation in Western Blotting.
