Which grade peptide should I choose?

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 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:
