Correlation matrix of PCA scores of samples from time 0, 90 and 120 minutes. Positive correlations are shown in blue, and negative correlations are shown in red. The dark blue diagonal line indicates the intersection of identical samples. The diagram illustrates the similarity of the protein spectra of the samples before and after treatment.
