3-(m-PEG8-Ethoxycarbonyl)Propanoic-NHS ester is a heterobifunctional PEG (polyethylene glycol) product that is commonly used for PEGylation. It contains a methoxy PEG chain with eight ethylene glycol units and an N-hydroxysuccinimide (NHS) ester group. The NHS ester group in 3-(M-PEG8-ethoxycarbonyl)propanoic-NHS ester allows for easy conjugation with amino groups present in proteins or peptides. It acts as a reactive linker that forms stable amide bonds between the PEG chain and the target molecule. The resulting PEGylated molecule exhibits improved pharmacokinetic properties, reduced immunogenicity.
