## Abstract We constructed a recombinant plasmid that can express the entire preβS2 sequence of hepatitis B surface antigen (HBsAg) as a fusion protein in __E. coli__. The hybrid protein, which comprises the bacterial TrpLE protein and the preβS2 sequence, was the prominent protein that was found i

## Abstract The infectious particles of hepatitis B virus (HBV) contain 3 related surface antigens, i.e., small, medium, and large, all of which are encoded by one large open reading frame with multiple initiation codons. The large surface antigen (LβAg) contains preS1, preS2, and S regions while b
The proteins of viral envelope, encoded by the pre-S1 region of HBV-DNA, were measured quantitatively with enzyme immunoassay using monoclonal antibodies directed to pre-S1 epitope and correlated with the expression of pre-S2 region encoded epitope and other HBV markers. In acute HBV infection, both
