Figure 3

Heat map representation of protein elution patterns generated for the later portion of the LC-MS analysis using tryptic peptides identified in each fraction. Observation counts of the peptides for each protein are used to derive relative protein abundances. The observation counts were normalized by dividing the value obtained for each protein with the sum of the values for the protein (row), with the scale ranging from 0 (i.e. least abundant, green) to 1 (i.e. most abundant, red). The columns in the heat map represent the RPLC fraction number.
