摘要
实时荧光定量PCR技术是一种新的核酸定量技术,通过检测PCR产物中荧光信号强度达到定量的目的,与常规PCR相比,具有无污染、特异性强、检测灵敏、定量准确等特点,该技术在分子诊断、动植物检疫等方面得到了广泛的应用。目前水产养殖业处于飞速发展时期,其中鱼类的病害问题也日益突出,为了预防和控制鱼类病害,实时荧光定量PCR技术已逐渐应用于鱼类病害的研究中。该文将从实时荧光定量PCR的技术原理、主要类型以及实时荧光定量PCR技术在鱼类病害研究的应用研究作一综述。
Real - time fluorescent quantitative ( Real - time PCR) is a new kind of nucleic acid technology, which can monitor the whole PCR process synchronously through the accumulation of fluorescence signal. The technology make PCR amplification and final product de- tection go on completely in closed condition, thus Real - time PCR is no pollution. On the other hand, it has such advantages as high sensi- bility, specificity and accuracy. So, Real- time PCR technology has been used widely indifferent fields. Currently, with the development of aquaculture, the disease of fish is more and more serious. In order to prevent and control the fish diseases, Real -time PCR technology was also introduced into and applied in fish disease research. This paper covers the development of Real - time PCR, its principle, types and features, furthermore, the application and prospects of Real - time PCR in fish diseases field were reviewed.
