Figure 4

Venn diagram representing the overlap of peaks between ProteinChip array types. CSF prepared in denaturing buffer was processed on CM10, Q10, H50 and IMAC30 ProteinChip arrays using (a) SPA, and (b) CHCA. Peaks with a signal-to-noise ratio of 3 or greater, between the m/z range of 25–20 kD, were considered. When assigning peak clusters across spectra, two peaks on different surfaces were assumed to be the same protein if both their respective m/z were within 0.3%.
