Anti-HA-tag Antibody

Engineered for routine detection of HA-tagged recombinant proteins, this unconjugated polyclonal reagent from Antibodies.com recognizes the influenza hemagglutinin (HA) epitope YPYDVPDYA, a nine-amino-acid tag commonly appended to fusion constructs for tracking expression, localization, and purification. Raised in rabbit, the antibody is supplied as 100 µl at 1 mg/ml in phosphate buffered saline (PBS) containing 15 mM sodium azide at approximately pH 7.2, and is validated for Western blot workflows on cell lysates and recombinant expression samples. The polyclonal format broadens recognition across the HA epitope, while the rabbit host pairs with widely used anti-rabbit secondary antibodies in standard immunoblotting. Aliquot on arrival to limit freeze-thaw cycles, store refrigerated, and protect from light. For research use only.
