FIG 3

Western blot analysis of thermolysin-resistant PrPSc generated by mb-PMCA. Brain homogenate from tg338 mice infected with 127S prions was serially diluted in uninfected tg338 brain lysate, as indicated, and submitted to a single round of mb-PMCA. The resulting products were treated with either PK (+PK) or thermolysin (+TL) before Western blot analysis. The thermolysin-resistant signals were quantified so as to measure the ratio of thermolysin-resistant PrPSc to total PrP present in the unseeded samples (U). The ratios are indicated (% PrPSc). Unseeded sample has been 10-fold diluted before loading on the Western blot. The figure is representative of the ratios observed in two independent experiments. Molecular masses (kDa) are indicated at left.
