| 中文摘要:目的分析蛋白A/G亲和层析柱在纯化抗HCV血清的影响因素，以便选择最佳使用条件提高Protein A/G亲和柱的利用效率。方法分别将抗HCV血清用不同处理方式、不同上样方式、不同使用次数的亲和柱进行纯化，并收集纯化样品进行检测、分析。 结果用饱和硫酸铵粗纯后，在蛋白A/G亲和层析柱的纯化效果更好；样品在亲和柱内吸附30min可提高亲和柱的对目的蛋白的吸附。 结论使用初纯的抗体并增加吸附时间能提高亲和层析柱的利用率，并有效延长亲和柱的使用寿命。 |

| Abstract:ObjectiveTo analyze the factors of Protein A/G affinity column,influencing purification effect, and get the best condition to improve application effect of Protein A/G affinity column. MethodsWe Purified anti-HCV-IgG serum with different disposal modality, different sample input modality and different application number of affinity column before detecting and analyzing the purified samples. ResultsThe Protein A/G affinity column had the best purified effect after using saturated ammonium sulfate to first purification, which increased the affinity column adsorption effect within 30 minutes adsorption. ConclusionUsing antibody with first purification and adding the adsorption time could improve utilization rate of affinity column and prolong the service life. |
