Overview

  • This PEP Search program allows a user to search the MS/MS spectra of both unlabeled and dimethyl labeled peptides to identify and confirm amino acid sequences of di/tripeptides. This program can also be used to search a MS/MS spectrum of an unlabeled di/tripeptide to generate a list of possible matches.


Features

  • A database consisting of all the sequences and predicted MS/MS spectra of 400 dipeptides and 8,000 tripeptides.


  • Uploading the CSV files of MS/MS spectra generated from the unlabeled and dimethyl labeled samples for automated search.


  • Entering the unlabeled di/tripeptide molecular ion mass and the fragment ion masses manually for database search to generate a list of possible sequence matches.
