A number of HBeAg ELISA kits are commercially available to enhance your infectious disease research. HBeAg, or hepatitis B e-antigen, is a soluble protein expressed by the hepatitis B virus (HBV). Because HBeAg is secreted and accumulates in the serum during infection, it is used as a marker for active HBV replication and infection. Inversely, the presence of anti-HBeAg antibodies has also been used to determine declining levels of infection. ELISA kits for detecting antigens or serum antibodies against HBeAg typically include prepackaged pre-coated strips or microplates, diluents, and detection antibodies.
