Figure 4From: Calculation of partial isotope incorporation into peptides measured by mass spectrometryA scatter plot of 90,637 peptide masses ( m/z ) and their decimal residuals of a Mycobacterium tuberculosis dataset after classification and data modification for unlabeled (0 atom %13C incorporation; light grey) and fully labeled (100 atom %13C incorporation; dark grey) peptide masses resulted. The two lines represent the slopes for the calculation of13C incorporation. The values of the two scatters are for the unlabeled b0% = 5.1357e-4 and b100% = 6.3347e-4 for fully labeled dataset. Numbers in each segment represent Daltons added to decimal residuals to achieve straight plot from figure 3 (for details see text).Back to article page
