| 摘 要： | 对猪瘟病毒(CSFV) C株、LT株E2基因主要抗原区在pGEX系列表达载体中原核表达的融合蛋白进行了变性、复性和纯化回收试验。用建立的变性、复性和纯化方法,获得了可溶性的纯化蛋白E2,其纯度达70%,回收率为10%。对复性纯化的E2蛋白进行了免疫活性检测,结果表明,其比未纯化蛋白的免疫活性高20倍左右。 |

| Abstract: | The fusion recombinant proteins of CSFV strain C and LT, which had been expressed with vector pGEX in Escherichia coli, were denatured, renatured and extracted experimentally. The results showed that the obtained E2 proteins were dissolvable and active, and their purification rate and the reco- very rate reached 70% and 10% respectively. Immunological activity of the renatured and purified E2 proteins was 20 times higher than the unpurified ones. |
| Keywords: | classical swine fever virus recombinant E2 protein inclusion body renaturation purification |
