QUICK LINKS
Methoxy PEG Succinimidyl Carboxymethyl Ester 2000 (mPEG-SCM 2000) is a derivative of polyethylene glycol (PEG) specifically designed for the functionalization and modification of proteins, peptides, and other molecules in biochemical research. This molecule plays a role in the PEGylation process, where it is used to improve the solubility, stability, and bioavailability of biomolecules. The succinimidyl ester group at one end of the PEG chain is highly reactive towards amine groups, making it an effective agent for forming stable amide bonds with lysine residues and the N-termini of peptides and proteins. This selective reactivity is vital for applications in protein conjugates, as it allows for the controlled attachment of PEG chains to specific sites on the target molecules. The methoxy group on the opposite end of the PEG chain enhances the hydrophilic nature of the conjugate, contributing to its increased solubility in aqueous environments.
