一般描述
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.
应用
聚乙二醇3000可用于：
- 作为单分散磁铁矿胶体磁性纳米颗粒合成中的表面改性剂。
- 作为木葡聚糖寡糖还原端特异性纤维二糖水解酶(oligoxyloglucan reducing-end specific cellobiohydrolase, OXG-RCBH)悬滴蒸气扩散法结晶中的沉淀剂。
- 作为溶剂和相转移催化剂(PTC)用于双水相络合萃取(aqueous biphasic reactive extraction)。
- 作为添加剂制备聚砜膜，用于孔径分析研究。

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
