摘要:

建立检测贝类中GⅠ、GⅡ、GⅣ和GⅤ型札幌病毒的实时荧光RT-PCR新方法。首先使用PEG 8000对贝类中的札幌病毒进行富集,然后采用Tri-reagent提取材料中的总RNA,针对札幌病毒RNA 3'端含Poly A尾的特点,使用带有Poly(dT)25的磁珠对病毒RNA进行纯化,用所获的高纯度RNA进行四种型别札幌病毒的实时荧光RT-PCR检测。该方法高效、灵敏,检测下限为101数量级拷贝,能够用于日常检验。

Abstract:

In order to detect GI, GII, GIV and GV sapoviruses in shellfish, a fluorescent real-time polymerase chain reaction (RT-PCR) asssy was developed. sapoviruses in shellfish were concentrated using polyethylene glycol 8000 (PEG 8000) first. Total RNA of sapoviruses from Shellfish were extracted with Tri-reagent and purified with Poly(dT)25 magnetic beads due to its 3’ Poly(A) tails. Four genotypes of RNA with high purity were determined using the fluorescent RT-PCR assay. This method is effective and sensitive to obtain 101 copies as the limit of detection. Therefore, this fluorescent RT-PCR can be used in daily detection.

Key words: sapovirus, RT-PCR, detection
