Storage Instructions -20°C; Always let come to room temperature before opening; be careful to limit exposure to moisture and restore under an inert atmosphere; stock solutions can be prepared with dry solvent and kept for several days (freeze when not in use). dPEG® pegylation compounds are generally hygroscopic and should be treated as such. This will be less noticeable with liquids, but the solids will become tacky and difficult to manipulate, if care is not taken to minimize air exposure. | |

MAL-dPEG®₄-(m-dPEG®₂₄)₃
MAL-dPEG®4-(m-dPEG®24)3, product number QBD-10456, is a sulfhydryl-reactive, branched polyethylene glycol (PEG) product built around a tris core that is useful for modifying 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®24)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®24)3 is simplified compared to the analysis of conjugates prepared with traditional dispersed PEG products.
