Sephadex 是一种凝胶过滤树脂,由葡聚糖与环氧氯丙烷交联而成。不同类型的 Sephadex 的交联度不同,因此溶胀度和分子分级范围也不同。 Sephadex G-25 是五种不同的 G 型之一,范围从用于小分子的 G-10 到用于较大分子的 G-75。 Sephadex G-25 有 4 种不同的粒径(粗、中、细和超细)。

Sephadex G-25 有不同的散装尺寸和方便的预包装形式。作为一种 BioProcess 树脂,Sephadex G-25 通过供应安全性和全面的技术和监管支持满足工业需求。

  • Quickly desalts, removes contaminants and transfers to a new buffer in a single step.
  • Excellent recovery and minimum sample dilution
  • Available in prepacked HiPrep Desalting and HiTrap Desalting columns for fast and convenient desalting
  • BioProcess resin supported for industrial applications and well-established for desalting and buffer exchange in industrial applications

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-25 is one of five different G-types ranging from G-10 for small molecules to G-75 for larger molecules. Sephadex G-25 is available in 4 different particle sizes (Coarse, Medium, Fine & Superfine).

Sephadex G-25 is available in different bulk pack sizes and convenient pre-packed formats. As a BioProcess resin, Sephadex G-25, meets industrial demands with security of supply and comprehensive technical and regulatory support.
