Specificity of the anti - idiotope antibody (anti - Id), 41RF5, was deter-mined with indirect enzyme-linked immunosorbent assay (ELISA). The results showedthat 41RF5 reacted only with 94D1 IgG2b, not with normal mouse IgG and other seven mousemonoclonal antibodies - five specific for erythrocytic stages of P. falciparum, one for erythrocyticstages of P. inui, and one for Dengue fever virus type III, which indicates that 41RF5 does recognizespecifically the idiotope of 94D1 monoclonal antibody. In 41RF5 heterohybrid culture supernatant,anti-Id titre measured by ELISA was above 1:1 280. Up to the present, the heterohybrid cell linehas been cultured stably for 16 months.展开更多
