th molecules have the form Methyl-PEGn-Maleimide, where the subscript "n" denotes 12 or 24 ethylene glycol units. The maleimide is spontaneously reactive with sulfhydryl (–SH) groups, providing for efficient PEGylation of proteins, peptides and other cysteine- or thiol-containing molecules.

MM(PEG)n, sulfhydryl-reactive maleimide-activated PEGylation Reagents

PEGylation Applications:

PEGylate amine surfaces
Add inert mass to proteins, immunogens, drug compounds and probes
Improve solubility (decrease aggregation) of proteins or peptides without affecting function
Protect proteins from proteolysis

Alternative Names for MM(PEG):

Mal-m-dPEG
Methyl-PEG-malemide
m-PEO-Mal
Maleimide PEG 600
PEG 1200 Maleimide
Maleimide-activated mPEG

Why PEGylate a protein or peptide?

PEG-containing reagents have been used to modify proteins to provide specific advantages. Protein PEGylation can improve the stability of the modified protein, protect it from proteolytic digestion, increase its half life in biological applications, mask it from causing an immunogenic response, decrease its antigenicity or potential toxicity, improve its solubility, diminish the potential for aggregation, and minimize interference for both in vitro and in vivo applications. Polyethylene glycol, also called polyethylene oxide (PEO), has these effects because it is nontoxic, nonimmunogenic, hydrophilic, water soluble and highly flexible.

Advantages of Discrete-length mPEG-NHS Ester Compounds

These reagents are specially synthesized as homogeneous compounds of discrete chain length and defined molecular weight. As such, they enable precise control and optimization of surface protein modification experiments. By contrast, typical preparations of PEG compounds are heterogeneous mixtures composed of multiple chain lengths and a range of molecular weights.

Highlights:

Maleimide-activated for efficient PEGylation of sulfhydryl groups at pH 6.5-7.5; reaction of maleimide group results in formation of stable, irreversible thioether bonds
Fully characterized PEGylation reagents with defined PEG chain lengths; molecules of discrete molecular weight for consistency of performance in protein-modification applications
Provided with either 12 or 24 ethylene glycol units, enabling modification procedures to be optimized for a specific application while retaining all the benefits associated with protein PEGylation
PEG spacer provides unique advantages, including increased stability, reduced tendency toward aggregation and reduced immunogenicity
Easy-to-follow instructions increase the likelihood of a successful outcome
