Anti-Hepatitis B Surface Antigen (HBsAg) Antibody

Available through Antibodies.com, this unconjugated monoclonal antibody targets the Hepatitis B Surface antigen and is produced in mouse hosts as an IgG1 isotype. Supplied as a Protein G purified preparation at 1 mg per vial, it is validated for ELISA workflows in hepatitis B research and serology assay development. The reagent performs well as a capture or detection reagent in immunoassays that probe viral envelope protein expression, vaccine immunogenicity studies, and diagnostic kit manufacturing.

Storage recommendations call for aliquoting upon arrival and keeping frozen at -20 °C to preserve long-term binding activity, with working aliquots refrigerated and protected from light. Each lot is quality-controlled for specificity to the surface antigen target, minimizing off-target reactivity in patient sample screening. Researchers handling this antibody should allow it to equilibrate before use and avoid repeated freeze-thaw cycles to maintain affinity. The unconjugated format offers flexibility for downstream labeling with biotin, horseradish peroxidase, or fluorophore conjugates depending on assay design.
