PEG3-bis(Amino-Tri-(Propargyl-PEG2-ethoxymethyl)-methane) is a crosslinker consisting of six propargyl groups. The propargyl groups can form triazole linkage with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
