Application

PEG for cross-linking and used in "click" chemistry reactions. PEGylated materials have found broad use in drug delivery systems, virology, and immunology, as the incorporation of PEG improves pharmacological properties such as increased water solubility, enhanced resistance to degradation (protein hydrolysis), increased circulation half-life, and reduced antigenicity. Polymer for preparing enzyme conjugates soluble in organic solvents; promising drug carrier.
