 摘要: 通过向环氧氯丙烷活化的Sepharose CL-6B中引入苯基,制备了Phenyl-Sepharose CL-6B凝胶并优化了偶联条件,以该合成的层析介质分离纯化了猪肝中的谷胱甘肽转硫酶。结果表明,在NaOH浓度为0.25 mol·L-1,苯酚加入量为0.5 mL·g-1凝胶,60 ℃下反应4.5 h的条件下,偶联效果最好,偶联率达到95.5%。用该疏水层析介质纯化猪肝中的谷胱甘肽转硫酶,活性回收率为54.54%,纯化倍数为2.6。

 Abstract: Sepharose CL-6B was activated with epichlorohydrin. Phenyl-Sepharose CL-6B was synthesized in the process of coupling phenyl to the activated Sepharose CL-6B. The optimal conditions were studied. The Glutathione S-transferases(GSTs) from liver was purified using synthesized Phenyl-Sepharose CL-6B. The result showed that the maximum coupling rate was 95.5% with 0.25 mol·L-1 NaOH,0.5 mL·g-1 phenol at 60 ℃ for 4.5 h. The GSTs activity recovery was 54.5% and the purification fold was 2.6.

 Key words: Phenyl-Sepharose CL-6B; coupling; purification;Glutathione S-transferases
