超大孔离子交换制备色谱分离纯化高活性凝血因子Ⅷ

, 2012
建立了一条从人血浆中分离高活性凝血因子Ⅷ(FⅧ)的纯化工艺。基于FⅧ和介质孔径的尺度比及其对蛋白质活性影响的分析,设计了以超大孔离子交换制备色谱为核心步骤的新型分离纯化工艺。分别进行超大孔离子交换色谱与传统离子交换色谱的条件优化,并对优化工艺所得产品进行了活性检测(底物显色法)和纯度检测(高效凝胶过滤和凝胶电泳)。结果表明,超大孔介质结构不但可以有效地保护蛋白质大分子结构,而且能够大幅度地提高制备色谱的传质速率,从而得到具有高凝血活性的FⅧ产品。FⅧ在超大孔制备色谱过程中的回收率(85 ...

APPLICATION OF THE CATION EXANGE RESIN MODIFIED BY THE METAL IONS IN THE ESTERIFICATIAN

, 2003
将催化精馏中常用作催化填料的强酸性阳离子交换树脂用金属离子负载修饰后,考察了树脂催化性能的改变及树脂结构对其催化性能的影响。实验表明,经修饰后树脂的催化能力都高于原树脂,在不分水的情况下,合成乙酸乙酯时乙酸的转化率最高可达73%,具有很好的选择性,金属离子能与树脂的磺酸基团产生络合,提高了树脂的催化性能,所形成的新酸中心不会被阳离子交换而失活 ...
