Propargyl-PEG1-SS-PEG1-propargyl Usage And Synthesis

Description

Propargyl-PEG1-SS-PEG1-propargyl is a homoebifunctional cleavable PEG linker containing two propargyl groups and a disulfide bond. The propargyl group can be reacted with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. Disulfide bond cn be cleaved with reducing agent.

Uses

Propargyl-PEG1-SS-PEG1-propargyl is a cleavable 2 unit PEG ADC linker used in the synthesis of antibody-drug conjugates (ADCs)[1]. Propargyl-PEG1-SS-PEG1-propargyl is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
