Recombinase Polymerase Amplification and its Applications in Parasite Detection

重组酶聚合酶扩增技术（RPA）是以T4噬菌体体内核酸复制机制为原理，以多种蛋白及酶参与的一种新型核酸等温扩增技术，可在37--42qC条件下，20min内将核酸扩增至可检测水平。具有较高的敏感性和特异性，且操作简单，可在非实验室条件下实现对核酸的快速检测。自2006年问世后，已广泛应用于农业、食品安全、医学和转基因检测等多个领域。本文综述了RPA技术的研究进展及其在寄生虫检测中的应用。

Recombinase polymerase amplification （RPA） is a recently-developed isothermal nucleic-acid- amplification technology that is based on the nucleic acid replication mechanism in T4 bacteriophage. With this technique, nucleic-acid templates can be amplified to measurable levels within 20 min at 37-42 ℃. The RPA process has high sensitivity and specificity, and is simple to operate, thus nucleic acids can be detected rapidly in non-laboratory conditions. Since its development in 2006, the RPA technique has been applied in agriculture, food safety, medicine, transgene detection, etc. In this review, we will give an overview on the research progress of RPA and its application in parasite detection.
