After a few days, the irradiated mouse was injected with nn-radioactive antigen A and a different a B, also non-radioactive. Subsequently, the spleen of the irradiated mouse was removed and the presence of plasma cells secreting Ab against the antigens was determined. experiment described in question 2? If so a. Would complement be used at any time in the when, be specific. (2pts) b. suppose one analyzed the spleen cells to find out how many had bound radioactive antigen A during the first part of the experiment and found 500 spleen cells, 3 had actually b the antigen. How would you explain this finding? (2pts) c. of the following results, which might you expect to see? (2pts) a. Equal numbers of plasma cells secreting Ab against A and B b. Many plasma cells secreting Ab against B but few or none secreting Ab against A c. No plasma cells secreting Ab against A or B d.
