Nsp9基因实时荧光定量PCR检测方法的建立及其在感染细胞过程中表达量的变化
Establishment of the Quantitative Real-time PCR Method for PRRSV Nsp9 Gene Rapid Detection and Its Expression in PRRSV Infected Cells
摘要
Abstract
The study was conducted to establish a quantitative Real-time PCR method for PRRSV Nsp 9 gene rapid detection and study its expression in PRRSV infected cells.A pair of specific primers targeted to Nsp9 of PRRSV was designed and a Real-time PCR method based on SYBR Green Ⅰ fluorescent was developed for the quantization of PRRSV.The melting curve analysis u-sing SYBR Green Ⅰ dye showed one specific peak,and no primer dimers peak was observed.No amplification was detected from HEV,SIV and PRV samples by this method.There was good re-producibility and low variation coefficient.The quantitative Real-time PCR method developed in this study would be useful for rapid laboratory diagnosis and epidemiology investigation of PRRSV.During the process of virus infecting cells,the expression level of Nsp9 increased gradu-ally,and it got the highest at 36 h.This study laid the theoretical basis to explore the law of virus replication and clinical vaccine production.关键词
