Application

  • Staudinger ligation reagent for the conjugation of amine and azide containing compounds or biomolecules.
  • The amine functionalized molecule first reacts with the phosphine through the activated pentafluorophenyl ester.The azide-molecule is then reacted with the newly labeled phosphine to form the iminophosphorane, and the aza-ylide is subsequently captured by the methyl ester to yield the covalent conjugated product.

Selective chemical reactions enacted within a cellular environment can be powerful tools for elucidating biological processes or engineering novel interactions. A chemical transformation that permits the selective formation of covalent adducts among richly functionalized biopolymers within a cellular context is

Azide Building Blocks for Chemical Ligation

Chemoselective ligation strategies are a key success factor for chemical biology research. Ligation techniques open pathways to fully synthetic large peptides and even proteins.

Staudinger Ligation

The reaction between an azide and a phosphine forming an aza-ylide was discovered almost a century ago by Nobel Prize laureate Herrmann Staudinger.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
