    • This disclosure describes related novel methods for Recombinase-Polymerase Amplification (RPA) of a target DNA that exploit the properties of recombinase and related proteins, to invade double-stranded DNA with single stranded homologous DNA permitting sequence specific priming of DNA polymerase reactions. The disclosed methods have the advantage of not requiring thermocycling or thermophilic enzymes, thus offering easy and affordable implementation and portability relative to other amplification methods. Further disclosed are conditions to enable real-time monitoring of RPA reactions, methods to regulate RPA reactions using light and otherwise, methods to determine the nature of amplified species without a need for gel electrophoresis, methods to improve and optimize signal to noise ratios in RPA reactions, methods to optimize oligonucleotide primer function, methods to control carry­over contamination, and methods to employ sequence-specific third `specificity' probes. Further described are novel properties and approaches for use of probes monitored by light in dynamic recombination environments.
    • 本公开描述了利用重组酶和相关蛋白质的特性的靶DNA的重组酶 - 聚合酶扩增(RPA)的相关新方法,以允许DNA聚合酶反应的序列特异性引发的单链同源DNA侵入双链DNA。 所公开的方法具有不需要热循环或嗜热酶的优点,因此相对于其它扩增方法提供了容易和可负担的实施和便携性。 进一步公开的是能够实时监测RPA反应的条件,使用光调节RPA反应的方法,否则,确定扩增物种的性质而不需要凝胶电泳的方法,改进和优化RPA中的信噪比的方法 反应,优化寡核苷酸引物功能的方法,控制携带污染的方法以及使用序列特异性第三“特异性”探针的方法。 进一步描述了在动态重组环境中使用由光监测的探针的新颖性质和方法。
