Anti-Hepatitis B Surface Antigen (HBsAg) Antibody

Distributed through AFMS in Saudi Arabia, this primary antibody from Antibodies.com is a mouse monoclonal reagent raised against native Hepatitis B surface antigen and supplied as a 1 mg aliquot of a Protein A purified, unconjugated IgG2a. It is designed for use in ELISA and immunofluorescence assay (IFA) workflows, and it specifically recognizes HBsAg subtypes ad and ay, with no cross-reactivity to normal human serum. The reagent is provided at greater than 90% purity and is intended for research use only, making it suitable for HBV serology assay development, viral antigen detection studies, and as a reliable reference reagent in hepatitis B immunology research. As a monoclonal, the antibody offers consistent lot-to-lot specificity compared with polyclonal alternatives, and its unconjugated format gives users flexibility to choose their own label or detection chemistry, including common HRP, biotin, or fluorescent secondary antibody pairs. Storage on receipt should follow standard cold-chain practice for protein reagents to preserve binding activity, and the product is shipped refrigerated with a typical 10–14 business day lead time from Cambridge, UK. Researchers working on hepatitis B diagnostics, vaccine development, or antiviral screening will appreciate the precise subtype coverage (ad and ay), which matches the most clinically relevant HBsAg strains circulating globally. For Saudi Arabian customers, AFMS serves as the local Antibodies.com distributor, providing regional ordering, technical support, and faster delivery across the Kingdom.
