MAP30 PCR 克隆子筛选 苦瓜
2008/1/8
摘要
根据已报道的序列,把苦瓜(Momordica charantia) MAP30基因成功克隆到原核表达载体pET28a(+)中,并对PCR快速检测阳性克隆进行了研究。结果表明,直接用菌落、菌液、酚氯仿处理过的菌液,以及提取的质粒进行PCR都可以成功地筛选阳性菌落。其中,酚氯仿处理过的菌液PCR与质粒PCR的结果最接近,而且比质粒PCR简单,因此可作为方便可靠的阳性克隆筛选的新方法。Abstr...

摘要以酵母基因组DNA为模板,通过PCR方法分别扩增出在5′端带有6xHis标签的gcn5和rpd3基因,将其克隆到pBV220质粒中,分别构建成表达质粒pBVgcn5和pBVrpd3,转化大肠杆菌(Escherichia coli)并进行诱导表达。SDS-PAGE显示,含重组质粒的菌株经热诱导后分别过量表达出约50kDa的蛋白。利用6xHis亲和层析纯化了这两种重组酶。对组蛋白乙酰基转移酶GCN...
