File Name : suppl figure 1.png Caption : fig. s1. the score plot of two sw48 and sw48 cells treated with 20 µg/ml panitumumab are presented. the median values of the scores indicated by the big circles, present an estimation of spectral variability. the median of two controls are close to each other. this is an indication that the spectra from these samples are quiet similar. the spectral differences are more significant for control1 and the 20 µg/ml panitumumab treated cells as their median value is far apart compared to the two controls.
