Abstract

The synthesis of 211 At labelled 3H11 monoclonal antibody was performed by an activation reaction of carboxy via paraastato - benzoic acid intermediate. Its specific radioactivity was 18. 5-61. 1kBq/μg . Its immunoactivity was measured by ELISA method. In vitro binding and cytotoxic experiments showed when the 211At - 3H11McAb concentration is raised

the cytotoxic effect increased and have obvious selectivity. The cytotoxic effect of 211At - 3H11 McAb to target cell M85 was higher than that of 211At - IgG and Na211At . If the M85 cells were cultured with 3H11 McAb or 3G9McAb for 1 h at first

the cytotoxic effect of 211At -3H11McAb was inhibited. The specific radioactivity of 211At - 3H11McAb and cytotoxic effect are also discussed.
