m-dPEG®48-MAL, product number 10932, is a thiol-reactive, monodispersed PEGylation reagent used for surface and biomolecule modification. One end of the PEG molecule is methyl-terminated. The opposite end possesses a 3-maleimido propanoic acid functional group that connects to the PEG spacer via an amide bond. The maleimide moiety reacts with sulfhydryl groups by the thiol-Michael addition reaction.

PEGylation with dPEG® Reagents

Quanta BioDesign’s single molecular weight, discrete-chain-length PEGylation reagents (we sell them under the dPEG® tradename) are different from traditional PEGylation reagents.

Most conventional PEGylation reagents are non-uniform (i.e., disperse) polymers. In contrast, Quanta BioDesign’s dPEG® PEGylation reagents have no dispersity (Ð = 1).

Many monodisperse PEGylation reagents are purified from complex polymerization reactions. Contradistinctively, Quanta BioDesign’s dPEG® products are synthesized from high-purity, uniform glycol starting materials. Thus, they are superior in quality to many monodisperse PEG products.

Quanta BioDesign’s dPEG® products provide all of the benefits of conventional PEGylation reagents. However, because our products have no dispersity, they afford the user a more straightforward analysis of conjugates made from them.

Frequently Asked Questions (about dPEG® products)

How do I use m-dPEG®48-MAL?

m-dPEG®48-MAL modifies surfaces and biomolecules containing free thiol (sulfhydryl) groups using standard maleimide chemistry. m-dPEG®48-MAL is amphiphilic. It dissolves in aqueous buffers and organic solvents such as acetonitrile, dichloromethane, DMSO, DMF, and N, N-dimethylacetamide (DMAC).

The maleimide-thiol reaction is quite fast. At pH 6.5 – 7.5, it is highly specific for sulfhydryl groups. To learn more about the thiol-Michael addition, please click this link.

Potential uses of m-dPEG®48-MAL include the following:

  • Coating nanoparticle surfaces that contain free thiols;
  • Modifying immunogenic biomolecules with surface-accessible, free thiols to reduce or eliminate immunogenicity; and,
  • Coating hydrogels with surface-accessible thiols.

Many other uses of this product are possible. The suggestions represent just a few ideas out of many that could be listed.
