Branched PEGs impart significant water solubility and thus produce compounds with reduced aggregation or surfaces with reduced non-specific binding in diagnostic applications. The PEGylation reagent itself is nonimmunogenic and non-toxic, passing these properties to the PEGylated biopharmaceutical. These PEGs are potentially very useful as drug/protein modifiers to specifically increase the hydrodynamic volume.
