Since 2014, when Red Glead Discovery acquired the peptide company Pepticon, we provide customized synthesis of exclusive and complex peptides of the highest quality and purity to industry and academia.

  • Synthesis of peptides using solid phase technology
  • Purification by preparative HPLC
  • Solution phase methods employed as complementary approaches
  • Up to 50–60 amino acid single chain peptides. Deliveries of longer peptides possible using chemical ligation techniques.
  • Non-natural amino acids & other building blocks on a custom basis

Our expertise enables informed design of new cost-effective synthetic routes for peptides, including selection of adequate resin, introduction of chemical modifications and effective ways of cyclization, for example.

We also offer design of peptides aimed at improving biological activity & profile, stability as well as physicochemical and pharmacokinetic properties.

Peptide Analysis

Quality control confirming chemical identity, amino acid sequence and amino-specific modifications is routinely performed on our produced peptides using HPLC, LC-MS, LC-MS/MS and NMR spectroscopy. Delivered peptide material is accompanied by a Certificate of Analysis. Additional documentation can be provided if requested by the client.

Analytical capabilities at RGD

  • Purity by HPLC-UV
  • Molecular mass and amino acid sequence by MS/MS
  • Purity, peptide content and acetate content by 1D 1H NMR
  • Amino acid sequence and/or 3D structure by 1H/13C/15N NMR
  • Impurity ID by LC-MS/MS and NMR
  • In-house NMR method for detection of small molecule impurities in peptide samples down to <0.1%. Quantitation and structural elucidation feasible

Examples of peptide analyses performed by trusted partners:

  • Non-chiral & chiral amino acid analysis, peptide content (elemental analysis)
