 Use of Bis-propargyl-PEG18


Bis-propargyl-PEG18 is a crosslinker containing two propargyl groups at each terminal end. The propargyl groups can be reacted with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield stable triazole linkages. PEG Linkers are useful in the development of antibody drug conjugates.
