Description

Features and Benefits

4-formyl-benzamido-dPEG^®₁₂-TFP ester contains a 4-formyl benzamido group on one end of a 12-unit discrete (single molecular weight) PEG spacer arm and a reactive TFP (2,3,5,6-tetrafluorophenyl) ester group on the other end. TFP ester permits conjugation to a free amine. The 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.
