Convert your proteins and peptides into Click Chemistry reactive form with this reagent.

While Click Chemistry involves reaction between terminal alkyne and azide, both azides and alkynes are very uncommon in nature. However, there are reagents to attach these fragments to abundant amino groups which are ubiquitous in the world of biomolecules. This azido-NHS ester is designed for the conversion of proteins, peptides, amino-DNA, and other amines into Click Chemistry reactive azides.
