葡聚糖凝胶 G—25是高等院校科研及实验教学中经常大量应用的试剂,经过再生可反复使用。国内市售的葡聚糖凝胶 G—25绝大部分为进口分装,价格较高。它的再生方法很多,其核心有两个:一、湿态保存于4℃冰箱内。二、用化学试剂乙醇、丙酮、乙醚脱水后于恒温80℃烤箱内干燥。不论用哪种方法操作起来都比较复杂且不经济。 Sephadex G-25 is often used in scientific research and experimental teaching of institutions of higher learning reagents, after regeneration can be used repeatedly. Most domestic G-25 Sephadex Gels for imported sub-packaging, the higher the price. It’s a lot of regeneration methods, its core has two: First, the wet state stored in a refrigerator at 4 ℃. Second, with chemical reagents ethanol, acetone, ether dehydration at a constant temperature 80 ℃ oven dry. Either way, it can be complicated and uneconomic to operate.
