陶一之说： “我们打算进一步搞清核蛋白调节病毒rna复制的机制。 - Viral rnas were extracted from virus - infected allantoic fluids using qiaamp mini - extraction kits . after reverse transcription , cdna was amplified using specific primers for each gene segment
用qiagen的rneasyrna试剂盒提取病毒rna后，逆助兴才李医‘笋脂硕圣‘老‘才转录合成cdna 。 - Other tests that detect the sars - coronavirus rna have largely focused on the use of nasopharyngeal aspirates , urine and stools . as reported , these tests only allow the identification of 30 % of the sars patients by the third day of disease
现时亦有测试sars冠状病毒rna的方法，但这些测试大多利用鼻液、尿液或粪便，一般要在发病后三天才可以进行验证，其准确度亦只约三成。 - The amplified e2 fragments of two hcv strains were all 1280bp in length by 2 % agrose gel electrophoresis . expected size of 1280bp of 2 fragments and their specificity were confirmed by restriction endonuclease digestion and then they were cloned respectively into pmd - 18t vector
以此病毒rna为模板，利用rt - pcr技术，扩增出了猪瘟野毒株hcv - jn 、 hcv - yc完整的e2基因，用pmd - 18t载体克隆，经电泳检测、酶切分析及pcr鉴定初步证实了所扩增片段的特异性。 - 2 . an up - dated method was employed to purify tumv in this research . using the protease k method , we acquired the viral genome - rna . a pair of specific primers was designed and synthesized based on the nucleotide sequences of tumv coat protein genes reported before and rt - pcr was used to clone the cp genes of the six tumv isolates
应用改进的芜菁花叶病毒的提取方法从病叶中提取病毒粒体，应用蛋白酶k法从病毒粒体中提取病毒rna基因组，根据已报道的tumv的cp基因序列，设计并合成了一对特异引物，利用rt - pcr法克隆了6个分离物的外壳蛋白基因，与克隆载体puc19连接后通过热激法转化大肠杆菌dh5 。
