Proteotypic Peptides


A demo dataset featuring tryptic proteotypic peptides of protein biomarkers for gastric cancers is available here. Search results will include peptide sequence, precursor mass/charge, fragment mass/charge, charge state, and other details tailored for identification on a SCIEX QTRAP instrument. Users can also download an Enhanced Specific Peptide (ESP) feature file with references to PeptideAtlas peptide identifiers. Additionally, a skyline file containing proteotypic peptide predictions can be downloaded for user customization based on experimental and instrumentation needs.
