Description: m-PEG3-S-PEG4-propargyl is a PEG linker containing a propargyl group. The propargyl groups can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield stable triazole linkages. The hydrophilic PEG spacer increases solubility in aqueous media.
