Relative locations of identified antibody peptides. Each horizontal black line represents a distinct peptide sequence. Trypsin was applied for the colorectal tumor MS/MS spectra assessment, and four different enzymes were applied for polyclonal antibody MS/MS spectra assessment. Both spectra sets were searched against the same antibody database constructed using tumor RNA-seq reads driven by TCGA. A, Antibody PSMs from colorectal tumor MS/MS data. B, Antibody PSMs from polyclonal antibody MS/MS data.
