Quality Control - Quality Assurance
The PolyPeptide Group guarantees the best available quality for all its peptides. We follow stringent, precise procedures to ensure complete identification and very high purity.Every PolyPeptide products must conform to strict analytical specifications before sales and shipment. Of course, a specific analytical data sheet of each batch is sent with every product.
Our bioactive peptides are controlled by : HPLC (periodically recontrolled), Amino acid analysis, Mass spectrometry
Net Peptide Content: our bioactive peptides are sold by net peptide weight as determined by amino acid analysis and/or UV. There is an important difference between peptide content and peptide purity. Peptides inevitably contain both counterions and residual water as they are isolated as salts (such as acetates) by lyophilisation.
So, even if a peptide is 98% pure, the net amount of peptide may only represent 70-85% of the total weight of the powder depending on its amino acid composition, last purification step and lyophilisation.
For instance, your order 5 mg of NPY from PolyPeptide. If the net peptide content is 80%, you will receive in fact at least 5/0.8= 6.25 mg of powder. The advantage for you is that you have the exact amount of peptide in your vial. Even if you work in a humid area where hydration can change the weight of the powder.
This makes quantitative comparisons of the results obtained in different laboratories possible and facilitates communication between them.To search a catalog product, click here.

Special Amino Acids and Building Blocks
From Research to Pilot Scale
Special amino acids and derivatives, organic building blocks and turn mimics are useful tools for your peptide design. We have accumulated great experience in expected properties of organic building blocks. They are available from our catalog, or can be developed by our chemists.
Over 600 unusual amino acids and organic building blocks in stock
featuring beta-amino acids, gamma-amino acids, aminobenzoic acids, polyethylene glycol spacers, statines, diamines and more, that illustrate our particular know-how in special peptide and peptidomimetic synthesis.Available in Electronic Formats
