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.
Aplicação
Poly(ethylene glycol) (PEG) has been used to determine the signaling role of NADPH oxidase 4 (Nox4) in the modulation of vascular endothelial growth factor (VEGF) expression. In the species-specific quantitative polymerase chain reaction (qPCR) to dilute lysates.
