Peptide mapping against sequence

Amino acid sequence confirmation by peptide mapping

Peptide mapping for confirmation of theoretical amino acid sequence – by MALDI-MS/MS or nano LC-MS/MS 

Are you looking for a service to map your peptides and confirm them to a theoretical aa sequence?

We digest your protein using Trypsin. This cleaves the sequence after Arg and Lys residues. The resulting peptide mixture is then :analyzed by either MALDI-MS/MS or nano LC-MS/MS. The observed peptides are mapped to the expected amino acid sequence.

Service includes:

  • We do in-gel trypsin digest and peptide mapping by MALDI-MS/MS or nano LC-MS/MS.
  • We compare with your theoretical amino acid sequence.
  • You obtain a sequence coverage map.
  • You obtain calculated sequence coverage in % (generally 20-100%).
  • Report is delivered within 4-8 days.
