Description

PEG6000 (Polyethylene Glycol 6000): Polyethylene glycol (PEG) is a condensation polymer of ethylene oxide and water. PEGs are susceptible to oxidative degradation in the presence of air. Minimizing exposure to elevated temperatures and oxygen, or the addition of antioxidants, may help reduce degradation.

PEG has been widely used in various biochemical and pharmaceutical applications, including protein precipitation, biomolecule purification and separation, protein conjugation, and cell hybridization. PEG is also commonly used as a cell fusion agent in hybridoma production.

PEG is incompatible with phenol and may reduce the antimicrobial activity of certain preservatives. It may also affect the stability or activity of some antibiotics, including penicillin and bacitracin, under specific conditions. In addition, PEG may be incompatible with compounds such as sorbitol, tannic acid, and salicylic acid, and may affect the integrity of certain plastics.
