Polyethylene Glycol, MP Biomedicals™

Description

Formed as a condensation polymer of ethylene oxide and water. Polyethylene Glycol, MP Biomedicals (PEG) has been used in many applications from medicine to industrial manufacturing, including the precipitation of proteins.

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
