SNPsig® EscapePLEX™ SARS-CoV-2

N-(Amino-PEG1)-N-bis(PEG2-propargyl) HCl salt is a crosslinker consisting of an amino group with two propargyl groups. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The propargyl groups can form triazole linkage with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
