    • 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。

    • The invention is drawn to isolating sequence variants of a genetic locus of interest using a modified iterative primer extension method. The nucleic acids analyzed are generally single stranded and have a reference sequence which is used as a basis for performing iterative single nucleotide extension reactions from a hybridized polymerization primer. The iterative polymerization reactions are configured such that polymerization of the strand will continue if the sequence of the nucleic acid being analyzed matches the reference sequence, whereas polymerization will be terminated if the nucleic acid being analyzed does not match the reference sequence. Nucleic acid strands that have mutations can be isolated using a variety of methods and sequenced to determine the precise identity of the mutation/polymorphism. By performing the method on both strands of the nucleic acid being analyzed, virtually all possible mutations can be identified.
    • 本发明是使用改进的迭代引物延伸方法来分离遗传基因座的序列变体。 分析的核酸通常是单链的,并且具有参考序列,其用作从杂交聚合引物进行迭代单核苷酸延伸反应的基础。 配置迭代聚合反应,使得如果被分析的核酸序列与参考序列匹配,则链的聚合将持续,而如果所分析的核酸与参考序列不一致则聚合将终止。 可以使用多种方法分离具有突变的核酸链,并测序以确定突变/多态性的精确同一性。 通过对正在分析的核酸的两条链进行该方法,实际上可以鉴定所有可能的突变。

    • The invention provides a method and materials for monitoring and isolating differentially expressed genes. In accordance with the method of the invention, differently labeled populations of DNAs from sources to be compared are competitively hybridized with reference DNA cloned on solid phase supports, e.g. microparticles, to provide a differential expression library which, in the preferred embodiment, may be manipulated by fluorescence-activated cell sorting (FACS). Monitoring the relative signal intensity of the different fluorescent labels on the microparticles permits quantitative analysis of expression levels relative to the reference DNA. The invention also provides a method for identifying and isolating rare genes. Populations of microparticles having relative signal intensities of interest can be isolated by FACS and the attached DNAs identified by sequencing, such as with massively parallel signature sequencing (MPSS), or with conventional DNA sequencing protocols.
