Cattle breeders are now able to screen and select cattle for specific features, such as the ability to produce high-quality milk or resist specific diseases. After six years of work by more than 300 r...
牛肠激酶轻链基因的克隆及其在大肠杆菌中的融合表达Cloning and Fusion Expression of Bovine Enterokinase Light Chain Gene in Escherichia Coli
牛肠激酶轻链 克隆 表达 自催化切割
2008/1/16
摘要为克隆表达牛肠激酶（enterokinase）轻链(EKL)编码基因，以期应用于融合蛋白的切割与纯化，从市售北方黄牛十二指肠组织中提取总RNA,以RT-PCR方法扩增其cDNA片段，将此片段克隆于pUCmT载体中，经过特异性限制性内切酶酶切分析片段正确后，进行全序列分析。结果表明,克隆的cDNA与GenBank上的序列相比完全一致，得到了编码正确的牛肠激酶轻链基因全序列。随后，将目的基因片段插...
