Sephadex G-75

Sephadex G-75 is well established gel filtration resin for desalting and buffer exchange of large biomolecules >80 000 molecular weight.

葡聚糖凝胶G-75是一种性能良好的凝胶过滤填料,用于对分子量 > 80000 的大生物分子进行脱盐和更换缓冲液。

  • 一步即可快速脱盐,去除污染物并转移到新的缓冲液中。
  • 适用于大生物分子(分子量 > 80000)的缓冲液更换和纯化
  • Sephadex G 范围内的最高排阻限度 80000
  • 经典凝胶过滤填料。

Sephadex 是通过将葡聚糖与表氯醇交联制备的凝胶过滤填料。不同类型的 Sephadex 的交联程度不同,因此其溶胀度和分子分离范围也不同。
