General description
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. Polyethylene glycol (PEG) is an eco-friendly, biodegradable polymer widely used in pharmaceuticals and cosmetics. Its non-toxic nature and versatility make it a sustainable choice, derived from renewable resources, contributing to greener product formulations. Click here for more information.
Application
Polyethylene glycol 3000 can be used as:
- A surface-modification agent in the synthesis of monodispersed magnetite colloidal magnetic nanoparticles.
- A precipitating agent in the crystallization of oligoxyloglucan reducing-end specific cellobiohydrolase (OXG-RCBH) by the hanging-drop vapor diffusion method.
- A solvent and phase-transfer catalyst (PTC) in the application of aqueous biphasic reactive extraction.
- An additive in the preparation of polysulfone membrane to study the porometry.

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
