Abstract: | A method for the preparation of highly specific conjugates on the basis of antibodies obtained as a result of dissociation of the immune complex HBsAg--anti-HBsAg, formed in vitro, is proposed. ELISA was performed according to Walters with some modifications in the concentration of the assay ingredients and in the time of incubation. The technique of the assay of blood sera for the presence of HBsAg with the use of reagents manufactured in the USSR has been worked out. |
