The ends of Propargyl-PEG-COOH molecular chain are carboxyl and propargyl, respectively. It is a PEGylated crosslinking agent. Under the activation of EDC or HATU, carboxylic acids can form stable amide bonds with amines. The alkynyl groups can react with azides to form triazole bonds by click-chemical reactions. PEG in the chain increases the solubility of the molecule in an aqueous environment. Propargyl-PEG-COOH is widely used in click chemical biological conjugates, biomarkers, chemical biology and antibody drug conjugates (ADCs). Propargyl-PEG-COOH is recommended for storage at -5℃, in a dry place and out of direct sunlight.
