Fig. 6From: Quick and improved immune responses to inactivated H9N2 avian influenza vaccine by purified active fraction of Albizia julibrissin saponinsEffect of AJSAF on cytokine secretion from splenocytes in the immunized mice. Splenocytes were incubated with Con A (48 h) or H9–Ag (72 h), and the supernatants were collected for detecting IL-2, IFN-γ, and IL-10 levels using ELISA kits. The values are presented as means ± SD (n = 6). Significant differences with IH9V alone group were designated as *P < 0.05, †P < 0.01, and ‡P < 0.001; those with CH9V group as #P < 0.01 and ¶P < 0.001Back to article page
