Acid-C18-D-Glu-PEG2-amide-PEG2-amine is a branched PEG linker with a terminal amine group and two terminal carboxylic acid groups. The amino (NH2) group is reactive with activated NHS esters or carboxylic acid in the presence of EDC or HATU. The terminal carboxylic acid groups can react with primary amine groups in the presence of activators (e.g. HATU) to form a stable amide bond. Reagent grade, for research use only.
