GE離子交換填料弱陰離子DEAE葡聚糖凝膠 A-25

強(qiáng)陽(yáng)S、SP、強(qiáng)陰Q、QAE、弱陽(yáng)CM、弱陰DEAE的區(qū)別在于使交換介質(zhì)守全離子化的PH范圍，較寬者為強(qiáng)，較窄者為弱，與結(jié)合強(qiáng)度無(wú)關(guān)。傳統(tǒng)的凝膠多數(shù)為弱陽(yáng)CM、弱陰DEAE，同樣的純化工作，可以用強(qiáng)陽(yáng)S、SP、強(qiáng)陰Q、QAE介質(zhì)替代。

50較25多孔，孔徑較大。對(duì)于分子量小于30，000者，25比50的載量高；30,000-100,000者，50則比25的載量高；大于100,000者，結(jié)合限于顆粒表面，25的載量更高。
