【摘要】 蛋白质等生物大分子在聚乙二醇双水相体系中分配系数不同,可依此而进行分离纯化。此法分离的选择性优于硫酸铵、丙酮分段等经典方法,且对蛋白质有保护作用。该法操作简便,处理量大,回收率高,正日益广泛的应用。更多还原

【Abstract】 Biological macromolecules can be separated and purified usingaqueous polyethylene glycol (PEG) two-phase system in which proteins to beseparated distribute in different partition coefficients. This technique has advan-tages of superior selectivity, the technique with higher recovery and more coven-ient to operate and scale-up更多还原
