细菌感受态细胞摄取和分泌DNA的相关性研究① I. 含有质粒的枯草芽孢杆菌自然感受态缺陷突变株的诱变和分离 Study of the Interrelations Between DNA Uptake and Secreting of Competent Bacterial Cells I. Mutagenesis and Isolation of Natural Competence-deficient Mutant from Containing Plasmid Bacillus subtilis
枯草芽孢杆菌 自然感受态缺陷突变株 诱变 筛选
2008/1/7
以携带pUB110质粒的枯草芽孢杆菌BR151菌株为出发菌株,利用亚硝基胍作诱变剂,直接在LB平板上进行诱变。从2949个菌落中筛选出一个转化频率低于出发菌株2~3个数量级的突变株,并对其营养缺陷型、UV的敏感性及Km抗性和质粒进行了检测,确证其转化能力降低为自然感受态缺陷而非营养缺陷型的改变或重组缺陷所致。
体内遗传标记成团肠杆菌固氮质粒pEA9in vivo Labelling of nif-plasmid pEA9 from Enterobacter agglomerans 339
成团肠杆菌 遗传标记 卡那霉素抗性 质粒消除 同源重组
2007/12/29
用卡那霉素抗性(Kanr)基因对成团肠杆菌固氮质粒pEA9进行活体遗传标记。将来自质粒pEA9的3.0 kb片段(nif ENX)克隆到pBR322载体中,再将卡那霉素抗性(Kanr)基因插入到3.0 kb的片段中,构建成供体质粒pST5。将该质粒转化到含有待标记质粒pEA9的E.a.339菌株中,然后在AP培养基中消除供体质粒,筛选得到40个失去了pST5并保持卡那霉素抗性的克隆,分析表明它们不...

摘要用引物延伸芯片法实现对转基因水稻中
生物芯片技术是生物技术和微制造技术的融合, 已广泛用于生命科学的研究及实践、医学科研及临床、药物设计、环境保护、农业、军事等各个领域。而基因芯片是生物芯片中的一种,是指将大量基因探针分子固定于支持物上,然后与标记的样品进行杂交,所以一次可对大量核酸分子进行检测分析,从而解决了传统核酸印迹杂交技术操作复杂、自动化程度低、检测目的分子数量少、效率低等不足。文章...
