When the antibody ratio and the denaturation ratio were measured and plotted as a scattergraph, classical scrapie, CH1641, and BSE isolates clustered into 3 distinct groups (Figure 2, panel A): 1) scrapie isolates displayed antibody ratios <2 and denaturation ratios were 0.02-0.13; 2) CH1641 samples had antibody ratios >2 and denaturation ratios were 0.06-0.29; and 3) BSE samples had antibody ratios >2, but denaturation ratios were >0.51.
This idea is of course related to how close the points on a scattergraph lie to the straight line drawn at 45[degrees] from the origin.
