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.
