Presence of proliferating T cells specific to p472 and absence of anti-p472 antibodies 1 week after vaccination with p472. (A) The proliferative response of splenocytes prepared from rats injected with p472 in CFA or with PBS in CFA to their specific antigen was compared with their proliferative response to the nonspecific antigen (OVA) in CFA or in the absence of antigen. Results are expressed as the mean cpm values of quadruplicate samples obtained from three different animals ± SEM. (B) Antibodies in the treated rats were assayed by ELISA. The amount of antibodies detected in the rats immunized with p472 in CFA was not significantly greater than in those injected with PBS in CFA. Results are expressed by mean values (expressed in arbitrary units) ± SEM obtained from three rats, each tested in triplicate at each of the indicated dilutions.
