摘要
以香石竹环斑病毒(Carnation ringspot virus,CRSV)的5个分离物为研究对象,分别建立了快速检测香石竹环斑病毒的多种PCR方法。结果表明,这些方法的灵敏度都比DAS-ELISA的灵敏度高,其中SYBR Green RT-PCR的灵敏度最高,可检测CRSV RNA的最低量是6.4pg。免疫磁珠RT-PCR(IMS-RT-PCR)和普通RT-PCR最低可从400ng的带毒叶片中检出CRSV,而免疫捕获RT-PCR(IC-RT-PCR)最低灵敏度可从40ng的带毒叶片中检出CRSV,是普通RT-PCR的10倍。
A few of PCR methods were established for the detecting 5 isolated strains of Carnation ringspot virus (CRSV). The results showed that the sensitivities of all the PCR methods were higher than those of DAS-ELISA,and among these methods, the SYBR Green RT-PCR was most sensitive with a minimum detectable limit of 6.4 pg RNA of CRSV in sample. The minimum detectable quantity of sample for CRSV detection needed by IMS-RT-PCR and RT-PCR were 400 ng,but IC-RT-PCR only needed 40 ng of sample and the minimum sensitivity of IC-RT-PCR is the normal RT-PCR of 10 times.
