Figure Lengend Snippet: Cellular responses. Splenocytes from immunized mice (1 mouse/group) were collected and stimulated either without (none), with pooled peptides of S (S peptides) or with Con A followed by detection of IFN-γ or IL-4 cytokines in triplicate using FluoroSpot assay. (A) FluoroSpot wells show the IFN-γ or IL-4 released/5 × 10 5 cells. (B) Spot-forming cells (SFC) from (A) were quantitated and calculated. Empty and slash columns indicate none and S peptides stimulations, respectively. The data are presented as mean ± SEM, and the statistical significance between the groups under peptide stimulation was analyzed using Student's t -test (* p < 0.05). (C) Stratified SFC ratios of IFN-γ (Th1) vs. IL-4 (Th2).
Article Snippet: Cellular immunity assay was performed using the Mouse IFN-γ/IL-4 FluoroSpot PLUS kit (Mabtech).
