MAL-dPEG®4-(m-dPEG®4)3, product number QBD-10416, is a sulfhydryl-reactive, branched polyethylene glycol (PEG) product built around a tris core that is designed to modify surfaces and biomolecules containing free thiols. Vector Laboratories, Inc. manufactures this monodispersed PEG product with a single molecular weight and discrete chain length and sells it under the dPEG® tradename. MAL-dPEG®4-(m-dPEG®4)3 increases the hydrophilicity of conjugated molecules; reduces non-specific, hydrophobic interactions; and decreases or eliminates the antigenicity of conjugates. Also, because it is a single molecule, the analysis of conjugates made with MAL-dPEG®4-(m-dPEG®4)3 is simplified compared to the analysis of conjugates prepared with traditional dispersed PEG products. The maleimide reactive group reacts rapidly and selectively with free thiols (i.e., sulfhydryl groups) in aqueous media at pH 6.5 – 7.5. The maleimide-thiol reaction is a type of “click chemistry.” However, above pH 7.5, maleimide groups react with free amines in addition to free thiols.
