Custom Synthesis Service

Although A.P.Noke offers more than 4000 amino acids, peptides and other related products available from stock, your project may require a product not listed in our catalogue.
Then contact our custom synthesis team and ask for an offer. Let our experienced scientists prepare the exact product you need.

  • Expertise: Our chemists can prepare compounds according to your specifications in any scale you need – from milligram to kilogram and ton quantities. We are experts in producing complicated amino acids and long and difficult peptides.
  • Quality: A.P.Noke is committed to using synthesis and purification strategies that yield products of the quality and purity you require. Our standard analytical package typically includes mass spectrometric analysis, amino acid analysis, and determination of purity (by RP-HPLC) and peptide content. A.P.Noke sets industry standards for high quality custom synthesis.
  • Efficient service: Our custom synthesis techniques in combination with high capacity and state-of-the-art production equipment allow short delivery times without compromising quality. You will get technical support with the design of your products and complex organic molecules. If you need a custom amino acid or peptide, please challenge us with your ideas and take advantage of our expertise.

Amino Acids

A.P.Noke has rich experience in research and manufacture of amino acids and their derivatives. Include Natural Amino Acids, Unnatural Amino Acids, Amino Alcohols, N-Methyl Amino Acids, Phosphorylated Amino Acids etc.
