Figure 2

Principle component analysis of 38 peak clusters from end stage study (ES) data. Samples from scrapie affected animals are indicated in red, and healthy controls are indicated in blue. The first principal component explains 33% and second principal component explains 18.3% of total variation in data. Both these components visually separated the groups, and much of disease related variation contributed on first (PC 1) and second (PC2) principal components.
