Summary
We demonstrated the constitutive polypeptides (PP) of Dane particles employing Western Blot and investigated the antibody response ability of HBV infected subjects to PreSl PP in comparison with other serum markers from HBV infected individuals. The results indicated that 1) the major reason for discrepant results may be related to the detergents used in the sample solutions and the degree of denaturation the samples had undergone;. 2) there are 12 bands in the PAGE-graph of Dane particles. By Western Blot it was confirmed that 5 PP (P24, P27, P36, P39, P42) are derived from S-open reading frame (S-ORF), P21 is associated with C-ORF, P24-25 possesses some epitopes of Pol protein, and P45 and P76 express similar epitopes to human IgG and IgMi and 3) the prevalence of anti-PreS1 PP was 17.24 % in the group of healthy persons following latent HBV infection, much higher than that of HBV infected patients (1.21 %). The above findings imply that antibody response ability of the host to PreS1 PP is attributing to the outcome of HBV infection. It may play an important role in the elimination of the virus.
