产品描述

葡聚糖凝胶,即Sephadex,是一种凝胶过滤树脂,一种具有三维网状结构的高分子化合物,由葡聚糖加入交联剂通过醚键互相交联聚合而成。不同类型的Sephadex的交联度不同,因此其溶胀度和分子分级范围也不同。交联度越大,网孔结构就越紧密,吸水后的体积膨胀就越小,能允许进入凝胶内部的分子的分子量也就越小,反之亦然。层析时,大于凝胶孔径的大分子,被阻于凝胶相外,沿着凝胶颗粒之间的间隙流动,下移速度最快,故最先被洗脱下来;中分子物质进入凝胶内部,洗脱速度为其次;而小分子物质因全部进入凝胶,所受阻力最大,故最后被洗脱下来,藉此原理物质得到分离。

性质

  • Quickly desalts, removes contaminants and transfers to a new buffer in a single step.
  • Classic gel filtration resin.

Sephadex is a gel filtration resin prepared by crosslinking dextran with epichlorohydrin. Different types of Sephadex differ in their degree of cross-linking and hence in their degree of swelling and their molecular fractionation range. Sephadex G-10 is one of five different G-types ranging from G-10 for small molecules to G-75 for larger molecules. Sephadex G-50 is available in 4 different particle sizes (Coarse, resin, Fine & Superfine) and Superfine has the smallest bead size for higher efficiency with shorter diffusion distances. Coarse and resin are are preferred for large scale group separations where high flow rates and low operating pressures are required.
