Figure 1

Illustration of ultrasonic velocity (dU) profiles of PK-untreated scrapie infected and healthy brain homogenates prepared at 2% in the presence and absence of plasminogen coated beads. Binding reaction was performed in the reaction buffer at 25°C. A 10 ul-buffer solution with coated beads (2 × 107) or without (0) was added to each sample (t = 0). Ultrasonic profiles of scrapie infected homogenate in the presence (black triangle) and absence (grey triangle) of beads and healthy brain homogenates in the presence (black circle) and absence of beads (grey circle) are shown over approximately 3-hour of the reaction.
