LAP analysis of T lymphocyte stimulation level. T lymphocyte proliferation in response to the inoculations with different proteins. T lymphocytes were isolated from the Guinea pig (N = 7) and stimulated with 146 S antigen or unstimulated in vitro, and the stimulation index was defined as the ratio of stimulated wells to unstimulated ones. T cell proliferation responses varied among all the groups.
