Figure 7: Gel electrophoresis on IFN- 𝛾 , IL-10, GATA-3, and GAPDH-amplified products. Total RNA was isolated from Splenocytes (a) or brain tissue (b) from WT and AhR-/- mice at 25 days after T gondii infection as described in Materials and Methods. The resulting fragments migrated along with the 200–500 bp fragment of the 100 kb marker used. The exact fragment sizes are listed in Table 1.
