Description_x000D_ Features and Benefits_x000D_ m-dPEG®12-TFP ester provides a variety of means to modify small molecules, peptides, proteins, and functionalized surfaces (metals, glass, and others). The single molecular weight methoxy-terminated dPEG® molecules are hydrophilic and non-immunogenic of exact length. Modification with m-dPEG® reagents can improve water solubility, increase hydrodynamic volume, eliminate or reduce non-specific binding, protect peptides and proteins from proteolysis, reduce or eliminate immunogenicity, and increase serum half-life in vivo. The m-dPEG®12-TFP (2,3,5,6-tetrafluorophenyl) ester reacts with amines._x000D_ Legal Information_x000D_ Products Protected under U.S. Patents # 7,888,536 B2_x000D_ dPEG is a registered trademark of Quanta BioDesign
