概述

Tween ® 20是属于聚山梨醇酯家族的一种聚氧乙烯山梨糖醇酯。它是一种分子量为1,225道尔顿的非离子型去污剂,假设有20个环氧乙烷单位、1个山梨糖醇和1个月桂酸作为主要脂肪酸。环氧乙烷亚基负责表面活性剂的亲水性,而烃链则提供了疏水环境。山梨糖醇可形成连接了环氧乙烷聚合物的骨架环。


应用

TWEEN 20广泛用于生化应用。它已用于: 作为用于制备稳定的水包油乳液的乳化剂 在膜的预提取中去除外周蛋白(以2%用于提取膜结合蛋白) 以典型的0.05%浓度作为基于膜的免疫检测封闭剂 按0.005至0.5%的浓度用于裂解哺乳动物细胞 与PBS一起在免疫组化技术中用于稀释抗体 用于在FISH(荧光 原位 杂交)技术中洗涤细胞 非离子洗涤剂


制备说明

TWEEN 20可与水混溶(100mg/mL),产生透明的黄色溶液。它还可与酒精、二恶烷和乙酸乙酯进行混溶。TWEEN 20不溶于液体石蜡和固定油。

ECO TWEEN® 20, also known as Polyoxyethylenesorbitan monolaurate, is a bio-based, nonionic detergent manufactured from a natural fatty acid. This surfactant, derived from natural sources, provides various functional advantages, such as detergency, emulsification, and wetting. Its versatility makes it well-suited for a variety of applications in biochemical and biological research, with common uses including cell lysis, protein extraction, nuclei isolation and cell fractionation. We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product is a biobased surfactant and is aligned with the 7th principle of Green Chemistry "Use of Renewable Feedstocks" and the 10th principle "Design for Degradation".
TWEEN 20 is a polyoxyethylene sorbitol ester that belongs to the polysorbate family. It is a nonionic detergent having a molecular weight of 1,225 daltons, assuming 20 ethylene oxide units, 1 sorbitol, and 1 lauric acid as the primary fatty acid. The ethylene oxide subunits are responsible for the hydrophilic nature of the surfactant, while the hydrocarbon chains provide the hydrophobic environment. Sorbitol forms the backbone ring to which the ethylene oxide polymers are attached.

备注
注意: TWEEN 20在高压灭菌下可能会不稳定,特别是在含有金属阳离子的缓冲溶液中。不推荐在没有进行属性改变测试的情况下进行高压灭菌。TWEEN 20对热较为敏感并在暴露于升高的温度下时会变暗。据报道,聚山梨醇酯与碱、重金属盐、酚和单宁酸不相容。它们还可能会降低多种保存剂的活性。聚山梨醇酯的水溶液在储存期间会经历自动氧化,以及由光、温度升高和硫酸铜所催化带来的改变。
