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

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。
