Abstract:

DNA amplification is essential to most nucleic acid testing(NAT). There is no doubt that polymerase chain reaction(PCR) is the benchmark technology for DNA amplification, but is mainly performed in centralized laboratories. Recombinase polymerase amplification(RPA), as one of the most promising isothermal amplification technologies, can break through laboratory boundaries for nucleic acid testing, since it is less instrument-dependent and easier access to resource-limited areas, namely, suitable for point-of-care testing(POCT) applications. As a developing technology, RPA also has several defects, which hind its widespread applications and development. Here, we make a summary on the principle and performance of RPA, with particular interest on the key process of the primer recombination and the dynamic balance of ATP that guide the eventual performance. Besides, several critical issues and potential points for further improving the performance of RPA were also summarized.

Key words: Recombinase polymerase amplification(RPA), DNA, Diagnosis, Point-of-care testing
