(Acid-PEG10)-Tri-(Azide-PEG10-ethoxymethyl)-methane is a PEG derivative which contains biotin and carboxylic acid moieties. Biotin can be used for the conjugation of proteins and biotin labeling. The carboxylic acid groups can undergo sequential amide coupling reaction with amine-bearing biomolecules in the presence of EDC, HATU and DCC to form stable amide bonds.
