Application

Polyethylene glycol 3000 can be used as:
  • A surface-modification agent in the synthesis of monodispersed magnetite colloidal magnetic nanoparticles.[1]
  • A precipitating agent in the crystallization of oligoxyloglucan reducing-end specific cellobiohydrolase (OXG-RCBH) by the hanging-drop vapor diffusion method.[2]
  • A solvent and phase-transfer catalyst (PTC) in the application of aqueous biphasic reactive extraction.[3]
  • An additive in the preparation of polysulfone membrane to study the porometry.[4]

    A novel xyloglucan-specific exo-beta-glycosidase, oligoxyloglucan reducing-end specific cellobiohydrolase (OXG-RCBH), recognizes the reducing end of oligoxyloglucan and releases two glucosyl residue segments from the main chain. OXG-RCBH was crystallized by the hanging-drop vapour-diffusion method with polyethylene glycol 3000 and polyethylene glycol
