The seeding activity (expressed as PrP27-30
equvalents in g/g tissue) in various tissues from different time-points after inioculation were measured by qRT-QuIC by using the formulas shown in Figure
c. The PrP27-30 concentration corresponding to 1 LD50 units per gram of tissue is represented by a gray broken line. Shown are the mean and s.e.m. (n = 5).
