Figure 4
Plasma PCA. PCA score plot of plasma samples from cloned pigs (closed symbols) and control pigs (open symbols) (a) and PC2 loading plot (b). n = 112. R2X = 0.97, Q2(cum) = 0.74 for the 10 component model. Major discriminatory resonances are marked with numbers that correspond to the identifications in figure 1. Asterisk denotes presumed threonine, which could not be resolved in the 1-D NMR spectrum.
