Effect of anti-LLO polyclonal antibody on IFN-γ production induced by rLLO529, rLSO530, or rLSO483. Normal spleen cells were stimulated with rLLO529, rLSO530, or rLSO483 (50 nM) for 24 h in the presence of anti-LLO polyclonal antibody or control rabbit immunoglobulin G (IgG) (5 μg/ml). The level of IFN-γ was measured by ELISA. Representative results are shown. Similar results were obtained in three independent experiments. The data are means ± standard errors for three determinations. An asterisk indicates that the results are significantly different from the control results (P < 0.05). PBS, phosphate-buffered saline.
