Peptide Purity

  • Our comprehensive range of high-quality amino acid derivatives available from stock allows us to carry out orders of unusual peptides according to your specificatons rapidly.
  • All custom peptides are manufactured at our state-of-the-art facilities.
  • Our custom-synthesized peptides are characterized by amino acid analysis and mass spectrometry. Their purity is determined by analytical RP-HPLC. A Certificate of Analysis containing these data will be made available to you upon delivery.


As the price of custom peptides will grow considerably with increasing purity demands, customers should order the purity required for their application. Our recommendations are:

  • NMR studies
  • Crystallography studies
  • Peptides used as reference in final quantitative studies
  • Enzyme-substrate studies
  • Receptor-ligand interaction studies
  • Blocking and competition assays
  • Production of monoclonal antibodies
  • Enzyme-substrate studies (quantitative)
  • Receptor-ligand interaction studies (quantitative)
  • Blocking and competition assays
    • ELISA and RIA (quantitative)
    • In vivo/in vitro studies
  • Western blotting studies (non-quantitative)
  • Enzyme-substrate studies (non-quantitative)
  • Phosphorylation studies
  • Production of polyclonal antibodies
  • Determination of the titer of antibodies in standard ELISA




When your project requirements advance from research scale to process development and cGMP manufacturing, Bachem is ready to support you with our framework of cGMP production facilities and dedicated regulatory affairs staff.
