Figure 3. In the upper part is the electropherogram view of a normal tear sample (also run on lane 6 of Figure 2), the molecular weight in kDa is on the x-axis, and the fluorescent intensity is on the y-axis. Peaks are identified for all samples and are tabulated by peak ID (numbers 1 to 17 at the top of each peak) in the customizable result table shown in the lower part. In this table, the size in kDa, the concentration in ng/μl, and the percentage versus total protein content for each peak are shown. **A shoulder peak for lactotransferrin is found in this analysis performed with the Protein 230 kit.
