Description

Features and Benefits

The m-dPEG^®₈-NHS 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^®₈-NHS ester reacts with amines.
