three envelope proteins called large (LHBs), middle (MHBs) and small hepatitis B surface antigens; and the regulatory X protein. Nucleic acid polymer, amphipathic oligonucleotide is currently ...

Assays for hepatitis B surface antigen (HBsAg) are the most frequently used tests to detect HBV infection. Vaccination for HBV can produce transiently detectable levels of HBsAg in patients.

Later, when transmissibility and an association with hepatitis B were demonstrated, the Australia antigen was shown to be the envelope protein of HBV. For many years, hepatitis B was recognized ...

and hepatitis B s antigen (HBsAg), which is HBV’s envelope protein. In addition to the excess HBsAg present in circulating virions, large amounts of subviral particles containing HBsAg are ...
