Custom peptide synthesis
Phosphorylated Peptides
Our expertise in Post-Translational Modifications (PTMs) such as phosphorylation spanning several years has helped in the research of phosphopeptides for several important biological applications.
Our chemists can incorporate single, or multiple combinations of phosphoserine (-pS-), phosphotyrosine (-pY-), or phosphothreonine (-pT-) residues into your custom peptide.
Typical location of phosphoryl groups
The addition of a phosphoryl group can occur on Serine (Ser), Threonine (Thr) and Tyrosine (Tyr) side chains via a phosphoester bond formation.
