Hepatitis B Surface Antigen (HBsAg-Ad) >90%

Supplied by Antibodies.com as a liquid preparation at the 1 mg pack size, this recombinant HBsAg-Ad subtype hepatitis B surface antigen is reported at greater than 90% purity by SDS-PAGE and HPLC analysis. The viral surface protein is intended for ELISA plate coating in hepatitis B serology workflows, supporting assay calibration, internal QC plate production, and standard curve generation for quantitative immunoassays.

Each vial ships from the Antibodies.com Cambridge facility, generally within a 10–14 business day window. For short-term handling, the liquid protein should be kept refrigerated between uses; longer-term stability is preserved by freezing aliquots at -20 °C and limiting freeze-thaw cycles. The reagent is sold for research use only and is not approved for diagnostic, therapeutic, or blood-bank screening applications. Matched anti-HBsAg capture and detection antibodies are available through the same catalogue for building complete paired immunoassay systems.
