Features and Benefits

m-dPEG48-amine is a methyl-terminated PEG amine compound. The PEG is a water-soluble, single molecular weight PEG product with a discrete chain length (dPEG). This dPEG linker is 146 atoms (173.1 Å) long, a monodisperse equivalent of a PEG2000. Carboxylic acids and their active esters react with the amino terminus to form amide bonds. Also, the amino terminus reacts with aldehydes and ketones, forming Schiff bonds, which are reducible to secondary amines. Uses for m-dPEG48-amine include modification of acid-functionalized surfaces and free carboxylic acid groups on biomolecules.

Many clinically used protein therapeutics are modified to increase their efficacy. Example modifications include the conjugation of cytotoxic drugs to monoclonal antibodies or poly(ethylene glycol) (PEG) to proteins and peptides. Monothiol-specific conjugation can be efficient and is often accomplished using
