Propargyl-NHS Ester (CCT-TA111)


Propargyl-NHS Ester is a simple alkyne-containing reagent that reacts with primary amines at pH 7-9 forming a stale amide bond. The terminal alkyne group reacts with azides by a mechanism known as the Cu-catalyzed click reaction enabling efficient and specific conjugation of derivatized molecules in biological samples. A short spacer arm adds minimal mass to modified molecules.
