Figure 7
3-D scores plot on PCs selected to demonstrate best segregation of MCF-7 cell IR spectra derived following 24-h exposure to Bu2Sn(L1)2, as indicated. IR spectra were collected using ATR-FTIR spectroscopy. Each spectrum was expressed in terms of chosen PCs using Pirouette software and rotated to identify segregation of different clusters. Each symbol represents a single spectrum as a single point in "hyperspace". The 3-D scores plot represents the segregation of cell populations following different exposures (i.e., vehicle control vs. 0.0001 μg/ml vs. 0.01 μg/ml vs. 1.0 μg/ml organotin(IV) carboxylate) on PC1, PC2 and PC3.
