    Purification of the Recombinant Human Lysozyme by Aqueous Two-Phase Extraction Coupled with Hydrophobic Interaction Chromatography

    • 摘要: 采用双水相萃取与疏水层析分离纯化重组巴氏毕赤酵母表达的基因工程人溶菌酶.通过正交实验方法研究了聚合物浓度、盐浓度和pH对双水相体系萃取人溶菌酶过程的影响.结果表明:当双水相萃取的pH为4,硫酸钠、氯化钠、PEG4000的质量浓度为0.13、0.06和0.08时,人溶菌酶上相回收率达98.8%,纯化因子18.0,浓缩因子3.6.双水相萃取后选用高效疏水层析色谱纯化人溶菌酶,经苯基高取代基介质疏水层析后得到纯化因子为22.7,收率为88.4%的人溶菌酶纯化产品,电泳纯度检测为100%.
