A fraction of PrP in the brains of Tg(WT-E3) mice is insoluble and can be immunoprecipitated by 15B3 antibody. A, Brain lysates prepared from mice of the following genotypes and ages were subjected to ultracentrifugation at 186,000 × g for 40 min, and PrP in the supernatants (S lanes) and pellets (P lanes) was analyzed by Western blotting using 6D11 antibody: non-Tg/Prnp+/+, 156 d (lanes 1–2); Tg(WT-E3+/−)/Prnp0/0, 162 d (lanes 3–4); Tg(WT-E3+/+)/Prnp0/0, 162 d (lanes 5–6); Tg(PG14+/−)/Prnp0/0, 156 d (lanes 7–8). B, Supernatant and pellet fractions obtained in B were subjected to immunoprecipitation using the monoclonal antibody 15B3. Immunoprecipitated PrP was analyzed by Western blotting with antibody 8H4.
