摘要:

利用试剂盒提取栗酒裂殖酵母的总DNA,以其为模板进行PCR克隆CDC2 基因,再将pBI121载体质粒和CDC2 基因进行Bam H I和Sma I双酶切,电泳分离和检测,最后连接目的片段构建重组载体pBI121-CDC2。克隆得到长度约为1.2 kb的CDC2 基因片段与NCBI网站所公开的CDC2 基因序列最大同源性达98%,所构建载体经酶切和PCR验证构建成功,并且在淡水舟形藻中得到表达,表明成功构建栗酒裂殖酵母CDC2 基因的淡水舟形藻表达载体。

Abstract:

Total DNA of Schizosaccharomyces pombe was extracted by kit and was used as a template for PCR to clone CDC2 gene. The plasmid pBI121 and CDC2 gene were double-enzyme digested with Bam H I and Sma I, isolated and verified by electrophoresis. At last, the vector of pBI121-CDC2 was constructed by linking the fragments. The 1.2 kb fragment which was obtained by cloning had 98% base similarity to the CDC2 gene of the website NCBI. The vector was digested and used for PCR to identify the successful constrction, and it was also expressed in freshwater Navicula. This showed that the freshwater Navicula expression vector with CDC2 gene was constructed successfully.
