| 摘 要： | 利用聚合酶链式反应(PCR)技术,从A型产气莫膜梭菌染色体基因组中扩增了1．2kb的α毒素基因。通过T4 DNA连接酶,将纯化的PCR产物与载体pGEM-T连接,转化受至体菌JM109中,经NcoI/EcoRI和BamHI/EcoRI双酶切分析,证明重组质粒pXCPA02中含有A型产气荚膜棱菌α毒素全基因。经核苷酸序列分析,明确了克隆的α毒素基因在重组质粒中的连接向位且核苷酸序列是正确的。

| Abstract: | Alpha-toxin gene was amplified from genomic DNA of Clostridium perfringens type A by polymerase chain reaction(PCR).PCR product was inserted into vector pGEM-T directively.The recombinant plasmid pXCPA02 was identified by restriction endonucleases Nco I/ Eco RI and Bam HI/ Eco RI analysis and nucleotide sequencing.The results showed that alpha-toxin gene fragment of 1.2kb has been cloned with a positive nucleotide sequence. |
