Fig 4. Analysis of IFN-γ and IL-4 by ELISPOT assays.

Fig 4

On day 14 following the second immunization, mice were sacrificed and single-cell suspensions were prepared from the spleen, cultured for 48 h, and stimulated with 5 μg/mL purified Ah01/AA viral antigen. IFN-γ (A) and IL-4 (B) secretion by splenocytes was determined by ELISPOT in triplicate wells. Values and bars represent means ± SD. ** p<0.001 compared to the PBS group.
