Description

Also known as PEG. Polyethylene Glycol, MP Biomedicals is a condensation polymer of ethylene oxide and water. It is used in precipitation of proteins, separating and purifying biomolecules, induction of cell hybridization, and as a fusing agent in enhanci

PEGs are susceptible to oxidative degradation in the presence of air. Minimizing the exposure of PEG to elevated temperatures and/or exposure to oxygen, or addition of an antioxidant can limit the amount of degradation. PEGs do not hydrolyze or deteriorate upon storage. PEGs do not support the growth of molds.
