Post-translational modifications (PTMs)
such as protein phosphorylation, protein methylation or protein acetylation play an important role in virtually all biological processes.
Therefore, the synthesis of post-translationally modified peptides (e.g. phosphopeptides or phosphorylated peptides, acetylated peptides, methylated peptides, peptides with citrulline or peptide glycosylation) is crucial for many projects.
JPT has extensive experience in peptide synthesis
of a large variety of post-translationally modified peptides, e.g. phosphopeptides and supplies post-translationally modified peptides for applications in proteomics, epigenetics and immunology. Let us know what kind of modifications you need, JPT's experts will be happy to discuss your requirements.
