Anti-Hepatitis B Surface Antigen (HBsAg) Antibody

Sourced from Antibodies.com, this affinity reagent is a Goat polyclonal antibody directed against the Hepatitis B Surface Antigen (HBsAg), targeting the ad and ay subtypes of the viral envelope glycoprotein. Raised in goat against HBsAg, the antibody is supplied as a liquid purified Ig fraction at a 500 µl pack size, unconjugated and intended for use as a primary antibody in laboratory immunoassays. The reagent is validated for ELISA, immunofluorescence (IFA) and Western blot (WB) workflows, making it suitable for routine serology screening, qualitative confirmatory testing, and detection of HBsAg in infected cell cultures or recombinant antigen preparations. Because it is unconjugated, it can be paired with a labelled secondary antibody of choice, such as AP-, HRP-, biotin- or FITC-conjugated donkey anti-Goat IgG reagents. With its polyclonal nature, the antibody recognizes multiple epitopes across the HBsAg molecule, providing broader reactivity toward circulating HBV strains. The product is intended for research use only and is shipped refrigerated from the Antibodies.com logistics network.
