From: The identification of disease-induced biomarkers in the urine of BSE infected cattle
Principle component analysis of different disease states followed throughout the disease progression. Ellipses have been drawn to illustrate the clustering of the 3 groups (BSE infected, control and normal). Within the infected group it can also be seen that the individual time points cluster together. A somewhat similar but less pronounced pattern is observed in the control samples. This analysis is based on the 56 spot features exhibiting statistically significant (ANOVA p < 0.01) changes in abundance and present on all 40 gel images. (PC1 = 38.6, PC2 = 23.0).
