SUMMARY Previously, it was reported that the immune response to myoglobin (Mb) was under genetic control, with the response to each site being under separate Ir ‐gene control. Here we have investigated the effect of antigen dose on the control of the antibody response to the five antigenic sites of sperm‐whale Mb to determine whether or not the overcoming of genetic control by antigen dose has a uniform effect on all five antigenic sites. The antibody response to sperm whale myoglobin (Mb) and its five antigenic was measured in the following inbred strains of mice, C57BL/6J, AKR and SWR/J. These strains of mice are low responders to Mb following immunization with 50 μg, responding only to site 4. After immunization with 200 μg Mb:C57BL/6J mice are high responders to Mb and respond to antigenic sites 1, 3,4 and 5; AKR mice are high responders to Mb and respond to antigenic sites 1 and 4; SWR/J mice are high responders to Mb and respond to all five antigenic sites. It was concluded that the genetic control of the immune response to Mb and its synthetic antigenic sites is dependent on antigen dose. Also, these studies have enabled us for the first time to separate the response to site 1 from the response to site 2 and thus have conclusively established that sites 1 and 2 are controlled by separate Ir ‐genes.
