【简单介绍】
GE离子交换填料弱阴离子DEAE葡聚糖凝胶A-25,强阳S、SP、强阴Q、QAE、弱阳CM、弱阴DEAE的区别在于使交换介质守全离子化的PH范围,较宽者为强,较窄者为弱,与结合强度无关。传统的凝胶多数为弱阳CM、弱阴DEAE,同样的纯化工作,可以用强阳S、SP、强阴Q、QAE介质替代。

GE离子交换填料弱阴离子DEAE葡聚糖凝胶 A-25描述:强阳S、SP、强阴Q、QAE、弱阳CM、弱阴DEAE的区别在于使交换介质守全离子化的PH范围,较宽者为强,较窄者为弱,与结合强度无关。传统的凝胶多数为弱阳CM、弱阴DEAE,同样的纯化工作,可以用强阳S、SP、强阴Q、QAE介质替代。
50较25多孔,孔径较大。对于分子量小于30,000者,25比50的载量高;30,000-100,000者,50则比25的载量高;大于100,000者,结合限于颗粒表面,25的载量更高。
