4 Sephadex LH20 样品的处理和洗脱溶剂的选择。 如果样品极性大,这选用反相溶剂洗脱(甲醇--水),样品用最少体积的甲醇--水(尽可能甲醇少一些)溶解,过滤后,湿法上样(一定要滤喔!要是把 Sephadex LH20 堵啦,就得将Sephadex LH20 的柱头部分弃去,很心痛呀)。如果样品极性小,这选用正相溶剂洗脱(氯仿--甲醇),...

A solvent system consisting of low-boiling organic solvents and ammonium hydroxide effectively separated iodoamino acids of the thyroid on Sephadex LH-20 gel filtration columns. The iodoamino acids were eluted from the column in a sequence unrelated to their molecular weights suggesting that adsorptive...
Sephadex LH-20柱层析 1. Tea polyphenols prepared from green tea was separated with the 95% ethanol elution onSephadex LH-20Column to obtain quercetin. 以体积分数95%乙醇作为洗脱溶剂,通过Sephadex LH-20柱层析从茶多酚中分离槲皮素,粗品得率为7。
