| 摘 要： | 用分子克隆技术从Thermococcus gorgonarius克隆并表达重组Tgo DNA聚合酶， 得到纯化的热稳定Tgo DNA聚合酶. 利用重组酶成功扩增了质粒pUC19、 野大麦Na+/H+逆向运转蛋白基因、 小鼠Cx37基因和人CYT2C9基因. 该酶的扩增性能与Taq酶相当， 而扩增忠实性分别比Taq酶、 Pfu酶高30倍和1.6倍.

| Abstract: | Thermostable Tgo DNA polymerase is obtained from Thermococcus gorgonarius by the molecular (cloning) and express technology. Plasmid19, wild barley Na~+/H~+ reverse transporter gene, mous Cx37 gene and human CYT2C9 gene were successfully amplified with recombinase. The amplification capability and (amplification) fidelity of the enzyme were compared with those of Taq enzyme. The result indicates that the (amplification) capability of Tgo enzyme is the same as that of Taq enzyme. But the amplification fidelity of Tgo enzyme is over 30 times higher than that of Taq enzyme and 1.6 times higher than that of Pfu. |
