Polyethylene Glycol, MP Biomedicals™

PEG has been used in a wide variety of biomedical and laboratory applications, including:

• The precipitation of proteins
• As a fusing agent in enhancing the effect of macrophages on hybridoma
• In the separation and purification of biomolecules
• In induction of cell hybridization
• To recover pathogenic viruses and human rotaviruses from water, oyster and sediment samples
• Demonstrated to have anticell proliferation and antitumor effects via induction of apoptosis

Utilization of PEG:

• PEGs are susceptible to oxidative degradation in the presence of air; minimizing exposure to elevated temperatures and 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
• PEG is incompatible with phenol and may reduce the antimicrobial action of other preservatives
