猪繁殖与呼吸道综合征病毒荧光定量PCR检测方法的研究
Establishment of Fluorescent Quantitative PCR Assay by TaqMan Probe Approach for PRRSV Detection
摘要
Abstract
The recombined plasmid pMD-ORF7 was constructed and used as standard positive template. And the FQ-PCR assay was constructed by quantitative concentration of serial 10 fold dilutions of pMD-ORF7 cDNA by optimizing circulation parameters. A standard curve was a-chieved. The result showed the sensitivity of this method was 1.0 ?10 0copy/ 祃. To detect three different samples by FQ-PCR repeatedly, the average circle threshold value was 0. 14, 0. 14 and 0.44, with the coefficient of variation of 0.01 % , 0.01 % and 0.02% , respectively. The FQ-PCR was proved to be with high sensitivity and repeatability. The detection of PRRSV in positive samples by both FQ-PCR and conventional RT-PCR was 100% , but the sensitivity of the former was 100 times higher than that of the latter.关键词
