FIG. 2.

IL-12 binding to LN cells and cell subsets from L. major-infected C3H mice. A two-color flow-cytometric analysis of IL-12 binding to lymphocyte subsets was performed with LN cells from C3H mice infected 2 days previously that were surface stained for CD4, CD8, or B220. Results show IL-12 binding by the total and gated populations. The peaks outlined by the dark solid lines and the shaded peaks are as defined in the legend for Fig. 1. These results are representative of four experiments.
