Methods for nucleic acid amplification with thermostable ribonuclease H, in which single-stranded RNA (-) is prepared from RNA (+) as a target nucleic acid and the copy number of the single-stranded RNA (-) is increased through the use of thermostable ribonuclease H in combination with non-thermostable RNA-dependent DNA polymerase, non-thermostable DNA-dependent DNA polymerase and non-thermostable DNA-dependent RNA polymerase. In these methods, the number of amplification cycles is well increased and the sensitivity of detection can, therefore, be improved, as compared with the conventional methods. Also provided are methods for the detection of a target nucleic acid from RNA copies of a specific nucleic acid, obtained by any of the amplification methods, and reagent kits for use in these methods. |
