The interesting gene fragment with ecori and noti were amplified by overlapping pcr , which inserted into vector plasmid ppic9k after degisted by ecori and noti , and the recombinant plasmid was transformed into competent dh5cc . positive clones were screened by pcr from the lb plate with amp . digesting analysis resulte shows that the interesting gene were inserted into the vector ppic9k with correct direction 目的基因经双酶切后连接载体ppic9k ，然后导入大肠杆菌dh5中，在含氨卞青霉素( amp )的lb板上用pcr反应筛选出阳性菌落，双酶切结果表明目的基因已插入载体中，且方向正确，测序结果进一步证明人巨细胞病毒重组基因表达质粒成功地克隆了目的基因片段。
Afcd s senior veterinary officer ( farm ) dr howard wong said the proposal of importing fertile eggs and developing local hatcheries were among the items discussed by the secretary for health , welfare and food with local experts at a meeting last saturday . the experts agreed that the proposal was sound in principle . however , traders had some doubts 渔护署高级兽医师（农场）王?熙说： ?生福利及食物局局长在上星期六与本地专家举行会议，其中一个讨论项目是关于入口受精鸡蛋及发展本地孵化场的建议，专家同意上述原则的方向正确。
The purified production was cloned into pmd18 - t vector . the cloned plasmids were transformed into jm109 . the specific recombinant plasimid was identified by molecular weight , pcr and restriction endonuclease analysis . the results indicated that the resultant construct contained the gene of ibdv a fragment at right orientation 经琼脂糖电泳检测，将大小与预计分子量一致的片段纯化后连接到pmd18 - t载体中，再转化到jm109感受态细胞，得到的转化子经分子量比较、 pcr鉴定和酶切分析筛选阳性克隆，结果表明，得到的阳性重组子中含有a节段全长基因，插入到载体中的方向正确。
