ELISPOT assays of M. tb-specific IFN-γ producing splenocytes in (r)BCGs-vaccinated mice. Eight weeks after vaccination, splenocytes were isolated and then incubated with purified Ag85A, ESAT-6, or PPD for ex vivo IFN-γ ELISPOT assay. Column diagram for mean number of spot-forming units (SFU) ± SD () were shown. ∗ or ∗∗∗ (one-way ANOVA).
