Figure 2. Western blotting of the brains of different genotypic mice inoculated with 22L prions.

Figure 2

Brains from terminally ill, 22L-inoculated Prnp0/+, Tg(MHM2Δ23-88)/Prnp0/+, and Tg(MHM2Δ23-88)/Prnp0/0 mice, and from asymptomatic, 22L-inoculated Tg(MHM2Δ23-88)/Prnp0/0 mice (sacrificed at 337 dpi) were subjected to Western blotting using M20 and 3F4 anti-PrP antibodies after treatment with or without PK. M20 antibodies detect wild-type and mutant PrPs. 3F4 antibody recognizes only the mutant PrP. The PK-resistant MHM2Δ23-88, or MHM2ScΔ23-88, is detectable in terminally ill, 22L-inoculated Tg(MHM2Δ23-88)/Prnp0/+ and Tg(MHM2Δ23-88)/Prnp0/0 mice, but not in asymptomatic, 22L-inoculated Tg(MHM2Δ23-88)/Prnp0/0 mice. β-actin is an internal control.
