PEG 8000, Technical Grade

Polyethylene Glycol (PEG) 8,000 is a polyether compound, a polymer of ethylene oxide and water, that is used in a wide variety of fields. It is low toxicity that can be used as a lubricating coat for various surfaces in aqueous and non-aqueous environments, a reagent used to create very high osmotic pressures in biochemistry, a polar stationary phase for gas chromatography and as a binder.

PEG's are susceptible to oxidative degradation. To limit the amount of degradation, minimize the exposure to elevated temperatures, oxygen or of an antioxidant. A single-step method is used for the activation of PEG for binding to polypeptides and proteins. PEG has been used in the precipitation of proteins to enhance the effect of macrophages on hybridoma, for separation and purification of biomolecules, and for induction of cell hybridization. PEG is incompatible with phenol and may reduce the antimicrobial action of other preservatives, along with penicillin and bacitracin that are inactivated by PEG. PEG is also incompatible with sorbitol, tannic acid and salicylic acid and may affect the integrity of plastics.

PEG is soluble in water (670 mg/ml, 20°C) and is also soluble in many polar solvents such as acetone, alcohols, and chlorinated solvents. It is insoluble in nonpolar solvents such as hydrocarbons.This product is not suitable for human consumption or therapeutic use.
