Development of TaqMan-qPCR for Detection of Helicobacter muridarum
摘要
Abstract
Objective To establish the sensitive and specific TaqMan-qPCR method for detection of Helicobacter muridarum.Method The specific primers were designed according to the Helicobacter muridarum gyrase B(GyrB) gene,specific fragment was amplified by PCR,and cloned into pMD-19T vector to construct the recombinant plasmid GyrB-19T,which was used as standard DNA of this qPCR method.The qPCR system was optimized and the sensitivity,specificity,repeatability and quantitative range of this method were evaluated.Result The quantitative standard curve from 2 × 108 copies/well to 2 × 102 copies/well of serial diluted plasmid DNAs showed that they had good liner correlation,the slope of the standard curve was-3.57,R2>0.996,and the lowest detection limit reached 2 × 102 copies/well.Conclusion This qPCR method showed high sensitivity,specificity and stability,which will be utilized for qualitativeand quantitative detection of Helicobacter muridarum.关键词
