FIG. 5.

Proliferative response of an MP-F2-specific TCC in the presence of PBMC or LCL as APC. APC were pulsed with antigens at 5 μg/ml or peptides (pep) at 10 μg/ml and irradiated before incubation with specific clones. r-MP65, recombinant MP65. Data are expressed as mean counts per minute for triplicate cultures from one experiment out of four independent experiments with similar results. Error bars indicate standard deviations. An asterisk indicates a significant difference (P < 0.01) between the mean counts per minute obtained in the presence of the indicated antigen and the mean counts per minute obtained in the absence of antigen (No Ag).
