Features and Benefits
4-formyl-benzamido-dPEG®12-EDA-MAL contains a 4-formyl benzamido group on one end of a 12-unit discrete (single molecular weight) PEG spacer arm and a reactive maleimide group on the other end. The maleimide group allows conjugation to a free sulfhydryl moiety. 4-formyl-benzamide is used to introduce an aldehyde group into a target molecule. The hydrophilic, non-immunogenic dPEG® spacer provides improved water solubility to the target molecule compared to spacers containing only hydrocarbons.
