Figure 4

Averaged spectra from a protein profiling biomarker disovery study. Human plasma (85 samples, in duplicate) was chromatographed on Q anion exchange beads using a decreasing pH gradient and final organic extraction. Aliquots were applied to CM10 ProteinChip arrays and mass spectra were acquired at low (left), medium (middle), and high (right) laser energies. Each spectrum is averaged from 170 spectra.
