A New Silicon Dioxide-Coated MALDI-ToF Sample Plate for Peptide Analysis

Figure 2

Comparisons of the mass shift levels from serum samples as obtained on coated and common plates. At a peak of 4170.1 Da and 5847.8 Da, the mass shift levels of the coated plate were greater than those of the common plate. For the remaining four peaks, the means of mass shift levels of the coated plate were lower than those of the common plate.
