Pierce™ MM(PEG)_n reagents are methyl-terminated PEG compounds activated with a maleimide group for covalent pegylation of sulfhydryls on proteins or assay surfaces.

• Choice of 12 and 24 ethylene glycol units, enabling modification procedures to be optimised for a specific application
• PEG spacer provides advantages that include increased stability, reduced tendency toward aggregation and reduced immunogenicity
• Maleimide activated for efficient PEGylation of primary amines at pH 6,5 to 7,5; reaction of maleimide group results in formation of stable, irreversible amide bonds
• Easy to follow instructions increase the likelihood of a successful outcome
