Sera from selected monkeys 441-92, 149-93, 337-91, and 42-93 were analyzed by ELISA for antibodies binding to gp120 IIIB and 1F7 expression. Macaques 441-91, 149-93, and 331-91 displayed in A, B, and C were inoculated with mAb 1F7; macaque 42-93 was inoculated with isotype control mAb TEPC 183 (D). Prevaccination bleeds and sera from the peak response after vaccination are compared for each monkey as described for Fig. 1. Determinations of triplicate ELISA readings are shown as mean and SD.
