Fmoc-N-amido-PEG-Succinimidyl Valerate, MW 3,400 is an amine-protected PEG polymer with a succinimidyl group. The molecule can react with amine group of lysine or other amino molecule. The Fmoc group can be deprotected under basic condition to obtain the free amine for further conjugations. The PEG spacer is hydrophilic and therefore increases the water solubility properties of the compound. Reagent grade, for research purpose.
