    • The present invention provides for amplification of one or more polynucleotides by multi-staged linear amplifications using one or more RNA polymerases. At each stage RNA transcripts are accumulated at a linear rate, so that multiple stages provide for faster than linear transcript accumulation. In one aspect, the invention provides for polynucleotide amplification by ligating hairpin adaptors to an end of polynucleotides wherein the hairpin adaptors each contain a promoter sequence oriented so that transcription proceeds in the direction of the loop of the hairpin adaptor. Upon transcription through such loop region and to the complementary strand a replicate is made of the promoter sequence as well as the polynucleotide, thereby permitting exponential amplification upon reverse transcription, second strand synthesis, and repetition of the above cycle. Preferably such amplification is carried out under isothermal reaction conditions.
    • 本发明通过使用一种或多种RNA聚合酶的多级线性扩增来提供一种或多种多核苷酸的扩增。 在每个阶段,RNA转录物以线性速率累积,使得多个阶段提供比线性转录物积累更快的阶段。 在一个方面,本发明通过将发夹衔接子连接到多核苷酸的末端来提供多核苷酸扩增,其中发夹衔接子各自含有取向的启动子序列,使得转录沿发夹衔接子的环的方向进行。 在通过这种环区转录和互补链时,由启动子序列以及多核苷酸重复,从而允许逆转录,第二链合成和上述循环的重复进行指数扩增。 优选地,这种扩增在等温反应条件下进行。
