摘要:选择市售的三种细胞裂解液(RNAiso Plus、TRNzol Plus和RNAOUT)和两种DNA/RNA共提试剂盒(柱式病毒RNA-DNA双提试剂盒、QeasyTM快速DNA/RNA共提试剂盒),分别提取猪繁殖与呼吸综合征病毒(PRRSV, JXA1-R)、猪瘟病毒(CSFV, HCLV)和乙型脑炎病毒(JEV, SA-14-14-2)三种病毒的RNA,通过琼脂糖凝胶电泳和Real-time PCR间接评价了所提取的RNA的质量。结果表明:对于琼脂糖凝胶电泳,上述三种细胞裂解液和QeasyTM快速DNA/RNA共提试剂盒对应的样本均可见清晰高亮的条带,可用于临床RNA病毒检测以及定性分析。对于Real-time PCR,QeasyTM快速DNA/RNA共提试剂盒组RNA相对水平最高,RNAiso Plus和TRNzol Plus两种细胞裂解液组其次,以上三种试剂可用于临床RNA病毒检测以及定量分析。28048 毕业论文关键词:RNA;提取方法;比较;临床样本
Comparison of several methods for extracting RNA from animal tissues by several commercialization kits
Abstract:Three commercially available cell lysates (RNAiso Plus, TRNzol Plus and RNAOUT) and two DNA / RNA co-kits (LC-DNA double-kit, QeasyTM rapid DNA / RNA co-kit) were selected to extract three animal RNA viruses(PRRSV, CSFV and JEV). The RNA quality was evaluated indirectly by agarose gel electrophoresis and Real-time PCR. The result shows, for agarose gel electrophoresis, the clearly and highlight bands can be seen above the groups of the three cell lysates and QeasyTM rapid DNA / RNA co-kit, which can be used for clinical RNA virus detection and qualitative analysis. For Real-time PCR, the RNA relative levels of the QeasyTM rapid DNA / RNA co-kit group is highest, and the two cell lysates groups(RNAiso Plus, TRNzol Plus) followed. The above three reagents can be used for clinical RNA virus detection and quantitative analysis.
