Post-translational modification (PTM) identification

    Identify and analyze PTMs in large-scale, 12 hour minimum ($564 internal, $720 external) per project.


1. List of modified and unmodified peptides with mass-shifts

Identify modified peptides along with the unmodified counterparts.

  • Deliverables:
    • reports generated by MODa (mass-shifts and peptide-spectral matches)

2. Mapping mass-shifts to post-translational modifications and substitutions

Mapping the mass-shifts identified in step 1. to actual post-translational modifications and/or substitutions

  • Deliverables:
    • Mass-shift to PTM mapping

3. Comprehensive list of all modified peptides

List of all peptides mapped to proteins along with the site of modification (i.e., Serine phosphorylation)

  • Deliverables:
    • Excel file that has list of all modified peptide-spectral matches
  • No labels
