超滤的应用

超滤是一种膜分离技术,它的特点是使用不对称多孔膜,根据分子的大小来分离溶液中的大分子物质与小分子物质。超滤尤其适用于大分子溶液的浓缩、不同种类的分子的纯化以及溶液交换等。超滤法是一种温和的、非变性的物理方法,比其它分离方法具有效率更高、更灵活的优点。

超滤法的典型应用
  • 对蛋白质、酶、DNA、单克隆抗体、免疫球蛋白进行浓缩和脱盐
  • 药物、激素分析
  • 从PCR扩增的DNA中去除引物
  • 去除标记的氨基酸和核苷酸
  • HPLC样品制备
  • 样品的除蛋白
  • 从生物体液、发酵肉汤培养基中纯化抗生素、激素、药物
  • 从细胞悬液、裂解液中回收生物分子对蛋白质、酶、细胞、DNA、生物分子、抗体和免疫球蛋白进行常规意义的实验室浓缩和脱盐
  • 哺乳动物细胞的收集
  • 清洗细胞、纯化病毒、去除细胞碎片、除热原
