摘  要:
[目的]构建联合表达气肿疽梭菌的鞭毛蛋白与分泌蛋白神经氨酸酶的方法,用以制备气肿疽生物工程亚单位疫苗。[方法]根据已公布的气肿疽梭菌FliA(C)和NanA序列设计引物,联合使用SOE-PCR与TD-PCR技术,建立融合基因FliA(C)-NanA的扩增方法。[结果]试验成功扩增出了融合基因FliA(C)-NanA。[结论]SOE-PCR方法无需在引物设计中加入酶切位点进行连接,降低了试验成本,且2个基因间未加入其他核酸序列,避免了表达出影响免疫效果的蛋白;TD-PCR的应用节省了试验时间,避免了筛选退火温度的繁琐步骤,解决了基因丢失的问题。

摘  要:
[Objective]In order to prepare gene engineering vaccines of blackleg,a method to combined express flagellin and secretory protein neuraminidase of Clostridium chauvoei was constructed.[Method]According to the published FliA(C) and NanA sequences of C.chauvoei,the primers were designed.Then using SOE-PCR combined with TD-PCR technology,the amplified method of fusion gene FliA(C)-NanA was constructed.[Result]The fusion gene FliA(C)-NanA was amplified successfully.[Conclusion] The SOE-PCR method without restriction sites to connect in the primer design,reduced the cost of the experiment,and between the two genes did not join the other nucleic acid sequences,to avoid the expression of protein affected immune effect;the application of TD-PCR saved the test time,and could avoid tedious steps for screening of annealing temperature and the gene loss problem.
