Description

General description

Poly(ethylene glycol) (PEG) is a non-ionic hydrophilic polymer and is available in different molecular weights. It helps in the purification and crystal growth of proteins and nucleic acids. PEG and dextran together result in aqueous polymer two phase system, which is required for the purification of biological materials. PEG also interacts with cell membrane, thereby allowing cell fusion.

Application

Polyethylene Glycol 1500 (PEG-1500) has been used to mediate cell fusion.

Physical form

Solution, filtered through 0.2 μm pore size membrane, 50% PEG 1500 (w/v) in 75 mM Hepes (pH 8.0), bottled under nitrogen, ready to use
