Dot plots of plasma concentrations of selected peptides corresponding to wheat germ agglutinin (WGA)-captured proteins: ADLS*GITGAR (Alhpa-1-antichymotrypsin, AACT341–350), HITSLEVIK (Platelet factor 4, PF454–62), LALDNGGLAR (Inter-alpha-trypsin inhibitor heavy chain 4, ITIH4429–438), LGPLVEQGR (Apolipoprotein E, APOE198–207), QLEQVIAK (Fibrinogen alpha chain, FIBA202–210), and SLGN*VIMVCR (Complement factor H, CFAH58–67) in 20 paired healthy control (HC), early-stage colorectal cancer (CRC), late-stage CRC samples. The intensity was normalized with peak area of spiked Bovine serum albumin (BSA). p < 0.0167 was considered statistically significant.
