A, Western blotting of the cerebella of
tg(PrPN-Dpl)/Prnp0/0,
tg(PrPΔpreOR)/Prnp0/0, and
tg(PrPΔOR)/Prnp0/0 mice. 30 μg of the total
proteins were loaded onto each lane. Lane 1, Zrch I
Prnp0/0 mice; lane 2, wild-type mice; lane
3, Zrch I Prnp0/+ mice; lane 4,
tg(PrPΔpreOR)/Prnp0/0 mice; lane 5,
tg(PrPΔOR)/Prnp0/0 mice; lane 6,
tg(MHM2Δ23-88)/Prnp0/0 mice; lane 7,
tg(PrPN-Dpl)/Prnp0/0 mice. B, in situ
hybridization of the cerebella of wild-type, Zrch I
Prnp0/0, tg(PrPN-Dpl)/Prnp0/0,
tg(PrPΔpreOR)/Prnp0/0, and
tg(PrPΔOR)/Prnp0/0 mice. Purkinje cells in Zrch I
Prnp0/0 mice show background staining with the PrP cRNA
probe. In contrast, strongly stained Purkinje cells are observed in wild-type,
tg(PrPN-Dpl)/Prnp0/0,
tg(PrPΔpreOR)/Prnp0/0, and
tg(PrPΔOR)/Prnp0/0 mice. Magnification, ×10;
inset magnification, ×50. C, Western blotting of the
PNGase F-treated homogenates of the cerebella from wild-type (lane 1,
100 μg of the total proteins), Ngsk Prnp0/0 (lane
2, 100 μg), Ngsk Prnp0/+ (lane 3, 100
μg), tg(PrPN-Dpl)/Prnp0/0 (lane 4, 200 μg),
and tg(Dpl32)/Prnp0/0 mice (lane 5, 100 μg)
using anti-Dpl FL176 antibodies.
