MAL-dPEG®4-(m-dPEG®4)3, product number 10416, is a sulfhydryl-reactive, branched polyethylene glycol (PEG) product that is useful for modifying surfaces and biomolecules containing free thiols. Quanta BioDesign, Ltd. 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.
