    • In a method for amplifying the specific nucleic acid sequence, a highly specific amplification which has low possibility of non-specific hybridization can be carried out. Highly stable reagents, the activities of which do not decrease in case of supply and storage, are also provided. Thermostable enzymes are used as RNA dependent DNA polymerase, DNA dependent DNA polymerase, DNA dependent RNA polymerase and ribonuclease H, which are required for the amplification system based on replicated RNA. Especially, it is preferable that a thermostable enzyme derived from Thermus thermophilus which has RNA dependent DNA polymerase activity, DNA dependent DNA polymerase activity and ribonuclease H activity, and thermostable DNA dependent RNA polymerase are used together. By this method, inactivation of enzymes are prevented by using thermostable enzymes, and the amplification can be carried out without sequential addition of enzymes.
    • 在扩增特异性核酸序列的方法中,可以进行非特异性杂交的可能性低的高度特异性扩增。 还提供了稳定的试剂,其供应和储存的活性不降低。 热稳定酶用作基于复制RNA的扩增系统所需的RNA依赖性DNA聚合酶,DNA依赖性DNA聚合酶,DNA依赖性RNA聚合酶和核糖核酸酶H。 特别优选共同使用具有RNA依赖性DNA聚合酶活性,DNA依赖性DNA聚合酶活性和核糖核酸酶H活性的嗜热栖热菌的热稳定性酶和耐热性DNA依赖型RNA聚合酶。 通过这种方法,通过使用热稳定酶来防止酶的失活,并且可以不依次加入酶进行扩增。
