TCO PEG acid, TOC PEG COOH, MW 5000

Description:

TCO PEG acid, TCO PEG COOH is a bifunctional TCO PEG derivative that has a carboxylic acid group. TCO (transcyclooctene) group reacts with tetrazine group fast and efficiently while carboxylic acid group can be used to react with many other groups such amines, hydroxyls, etc. The reaction of TCO and tetrazine is a bioorthogaonal reaction that enables the conjugation of two molecules in aqueous solution fast and efficiently. PEG TCO derivatives have excellent water solubility, possess fast kinetics and stability in aqueous buffer. They are one of the best pegylation reagents to modify proteins, peptides, antibodies, biopolymers and particles via copper free Click Chemistry reaction.
