Propargyl-PEG4-NHS ester Chemical Properties, Uses, Production
Description
Propargyl-PEG4-NHS ester is an amine reactive PEG linker with an alkyne group. Under the copper catalyzation, alkyne group can react with azide-bearing biomolecules to form a stable triazole linkage. The hydrophilic PEG spacer increases solubility in aqueous media.
Uses
Propargyl-PEG4-NHS ester is a nonclaevable 4-unit PEG linker for antibody-agent-conjugation (ADC). Propargyl-PEG4-NHS ester is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
