Abstract
Injection of mice with immune complexes formed with bovine serum albumin (BSA) and rabbit anti-BSA in antigen excess produced an enhanced anti-BSA response. An enhanced antibody response was also obtained when immune complexes prepared at equivalence were injected intravenously and a second antigen injection was made within 4 days. The results suggest that immune complexes elicit within a few days a "primed state" which is identical to the primed state observed weeks after a single antigen injection; that is, the kinetics of the appearance of antibody and the effect of whole-body irradiation upon the antibody response following the second antigen injection were similar to those observed in mice primed with antigen alone. The role of antibody and antigen-antibody complexes in eliciting a primed state is discussed.
