Propargyl-PEG1-SS-alcohol is a Click Chemistry-ready crosslinker containing a propargyl group, a hydroxyl group and a cleavable disulfide bond. The propargyl groups can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield stable triazole linkages. The hydroxyl group enables further derivatization or replacement with other reactive functional groups.
Propargyl-PEG1-SS-alcohol is a cleavable 1 unit PEG ADC linker used in the synthesis of antibody-drug conjugates (ADCs)[1]. Propargyl-PEG1-SS-alcohol is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
