The influence of pH, ionic strength (I) and flow-rate of eluent on the chromatographic parameters of 5-fluorouracil (5-FU) on Sephadex G-10 columns was studied. Using an optimized phosphate buffer (pH 7.0, I 0.12), 5-FU showed reversible adsorption on the gel matrix and can be ...
1 Sephadex G型葡聚糖凝胶只适合在水中使用,Sephadex G-25羟丙化后就是Sephadex LH-20。其既有分子筛作用,在由极性与非极性溶剂组成的溶剂中还有反相层析效果。虽然价位很高,但由于性能颇佳,可再生利用,所以倍受亲睐。此外上柱样品损失很少,对处理小样品 1 Sephadex G型葡聚糖凝胶只适合在水中使用,Sephadex G-25羟...
(7)填料反复使用,每次用完,一般可用甲醇将柱子洗干净,然后用下一次分离的起步溶剂将甲醇替换出来,待用。 Sephadex LH-20是由葡聚糖G-25羟丙基化加工而成,属于分子筛凝胶,尤其适用于天然产物在有机溶剂中的纯化。例如:类固醇、萜类、脂类以及小分子多肽等,Pharmadex LH-20同时适用于分子类别非常相似的物质的分离和...
