Figure 3From: Limitations in SELDI-TOF MS whole serum proteomic profiling with IMAC surface to specifically detect colorectal cancer Detection of two proteins in the mass pattern of serum. (A) Representative mass spectra showing the two peaks of the classifier at m/z 3961 and m/z 5200. The top two spectra were cancer, and the bottom two spectra were non-cancerous control. (B, C) Cluster plots generated using IMAC 30 ProteinChip for the two peaks of interest. Dotted line, mean peak intensity.Back to article page
