Fig. 3From: Oral pre-administration of Purslane polysaccharides enhance immune responses to inactivated foot-and-mouth disease vaccine in miceEffects of POL-P3b on cytokines in mice immunized with O type FMD inactivated vaccine. The concentrations of IFN-γ, IL-2, IL-4 and IL-6 were measured using commercially available ELISA-kits according to the manufacturer’s protocol. Data were expressed as mean ± SD (n = 10). ○P < 0.05, ●P < 0.01, compared with control; ▲P < 0.05, ★P < 0.01, compared with FMDV. The detection limits of these assays were 2 pg/mL (IL-2, IL-4 and IL-6) and 7 pg/mL (IFN-γ), respectivelyBack to article page
