Abstract:
:An enzyme-linked immunosorbent assay (ELISA) was developed for screening production of monoclonal antibodies with specificity for HBsAg. Mouse hybridoma IgG were firstly extracted from assay medium with goat anti-mouse IgG adsorbed on polystyrene beads. The specific antibody was revealed by saturation with HBs antigen from human positive sera followed by reaction with specific sheep anti-HBs antibody conjugated with peroxidase. The sensitivity was of the order of 0.5-1 ng/ml specific antibody and specificity was satisfactory. The assay permits easy identification of determinant specificity on screening.
