Polyethylene glycol is used as an excipent in pharmaceutical products. It is used in the precipitation of proteins as well as in the separation and purification of biomolecules and in the induction of cell hybridization. It acts as a fusing agent to enhance the effect of macrophages on hybridoma; as a vascular agent in preclinical work; as an anti-foaming agent in food and as the gate insulator in an electric double-layer transistor to enhance superconductivity in an insulator.
