Detecting Hepatitis B Surface Antigen Mutants
Emerging Infectious Diseases, 2006 Hepatitis B viral mutants can emerge in patients as a result of selection pressure from either immune response or treatment options. Mutations that occur within the immunodominant epitopes of hepatitis B surface antigen (HBsAg) allow mutant virus to ...

Proteins of hepatitis B surface antigen [PDF]
Journal of Virology, 1977 Purified 22-nm forms of hepatitis B surface antigen (Hbsag) representing the three major antigenic subtypes (adw, ayw, and adr) were analyzed for their constituent polypeptides by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. No consistent difference in either the number or relative distributions of the polypeptides was observed for the ...

Stopping nucleos(t)ide analog treatment in chronic hepatitis B — Who and when?
Liver Research, 2017 Nucleos(t)ide analogs (NAs) are one of the first-line treatments for chronic hepatitis B (CHB) infection. NAs are highly efficient in suppressing viral replication but are associated with a low rate of hepatitis B surface antigen (HBsAg) seroclearance ...
