Analysis of peptides of HBsAg and the Epitopes of "a" Determinant by Monoclonal Antihody
Abstract: Five selected McAbs were tested for their binding to HBsAg polypeptidecomposition by using Western Blot. McAb B_6, B_9 and B_(12) combined polypeptideP24 of HBsAg, while McAb A_1 and B_(13) combined both polypeptide p24 andP27 of HBsAg. Using the five McAbs, the epitope density of "a" determinantof HBsAg derived from different sources was also studied with the second an-tibody method. The result showed that there was similar density of epitopesagainst five McAbs on plasma-derived HBsAg (PD HBsAg), CHO cell-...
