Custom Peptide Synthesis

CPC Scientific is one of the premier custom peptide producers in the world and we are proud to offer consistently reliable, high quality peptides directly to researchers. Although CPC offers thousands of ready-to-ship catalog peptides, many of our orders require custom synthesis. We can produce peptides from 2 to >200 AAs in length at purities from 80% up to 99%. We can perform virtually any peptide modification. Some of these peptide types and modifications include:

  • FRET and TR-FRET Substrates
  • Stable Isotope-labeled Peptides
  • Hydrocarbon and Triazole Staples
  • Peptide Macrocycles
  • Click Peptides
  • Dye and Fluorescent Labels
  • PEGylation (mono- and polydispersed)
  • Metal Chelating Conjugates
  • Multiple Disulfide Bonds
  • Glycosylation
  • Phosphorylation
  • Sulfation and Sulfonation
  • Incorporation of Unnatural Amino Acids
  • Lipidation
  • N-Terminal Modifications
  • C-Terminal Modifications
  • Hydrophobic Sequences
  • Peptoids
  • Rhodamine 110 Labeled
  • Cell-Penetrating Peptides
  • Long Sequences
  • Native Chemical Ligation
  • Epitope Mapping
  • Peptide Libraries
  • Neoantigen-based Libraries
  • Protein Conjugation
  • Selenocysteine
  • Depsipeptides
  • Peptidomimetics
  • Multiple Antigenic Peptides (MAPs)
