Protein identification and quantification. A. Number of protein identifications for each gel slice for IGD (blue), WG (orange), total number of protein IDs in each gel slice (green) and the number of proteins identified in both gel slices (purple) for human HCT116 cell lysate and B. for mouse tumor tissue lysate. C. Spectral counts of proteins identified in both slice IGD and WG plotted for all 5 slice pairs combined for human CRC cell lysate. The line is a linear fit to the data, the slope and corresponding R² value of the fit are indicated.
