Comparison of PrPSc and prion infectivity between the crude homogenate and 20K-sup. (A) Comparison of PrPSc amounts between the crude homogenate and 20K-sup. The relative protein load in each lane is indicated on the top. Nl indicates the uninfected mouse brain. PrP was detected with anti-PrP mAb SAF84; 1x indicates 0.25 mg brain equivalent. Molecular markers are indicated on the left side of the blot. (B) The relationship between incubation time (mean days ± standard error) and infectious units (log LD50/gram of the brain) in mice inoculated with serial dilutions of the crude homogenate (black circles and solid line; y = 16.642 – 0.061312x, where y is log LD50 and x is the incubation period) and the 20K-sup (blue squares and dotted line y = 17.474 – 0.060916x).
