The total RNA of cone snail was detected by agarose gel electrophoresis,NanoDrop^(TM) 2000 spectrophotometer and Aligent 2100 biological analyzer. [Results]The total RNA extracted from different tissues of cone snail showed clear band,and thus had similar concentrations and purity,and the highest yield was obtained from venom tube. [Conclusions] The total RNA extracted from different tissue parts of cone snail could meet the basic requirements of molecular biology,and its venom tube was the best tissue part for extracting total RNA,which lays a foundation for molecular biology research such as high-throughput transcriptome sequencing of cone snail.展开更多
采用改良的Trizol法提取厚皮甜瓜‘银帝’果实中的RNA.利用琼脂糖凝胶电泳、紫外分光光度法和RT-PCR法进行纯度、浓度和RNA完整性检测.结果表明：1 mL Trizol用于提取200 mg甜瓜果实量时,得到的RNA产量最大,氯仿抽提2次时提取到的RNA的A...采用改良的Trizol法提取厚皮甜瓜‘银帝’果实中的RNA.利用琼脂糖凝胶电泳、紫外分光光度法和RT-PCR法进行纯度、浓度和RNA完整性检测.结果表明：1 mL Trizol用于提取200 mg甜瓜果实量时,得到的RNA产量最大,氯仿抽提2次时提取到的RNA的A260/A280在1.9-2.0之间,所提取的RNA无蛋白质和DNA污染,室温沉淀和低温沉淀对RNA的产量无明显影响.将提取的RNA反转录后扩增β-actin基因片段,扩增的条带与设计大小一致,验证了该方法提取的RNA可用于RT-PCR.展开更多
紫肉甘薯块根富含多糖、多酚、淀粉、蛋白质和色素等物质,会影响紫肉甘薯块根总RNA的提取。本研究对五种不同的RNA提取方法进行比较,分析各自的优缺点,并对所得总RNA的浓度和纯度进行测定。研究结果表明,改良CTAB法和华越洋试剂盒提取...紫肉甘薯块根富含多糖、多酚、淀粉、蛋白质和色素等物质,会影响紫肉甘薯块根总RNA的提取。本研究对五种不同的RNA提取方法进行比较,分析各自的优缺点,并对所得总RNA的浓度和纯度进行测定。研究结果表明,改良CTAB法和华越洋试剂盒提取法均能提取出浓度、纯度较高的RNA,且RNA可用于反转录,并扩增出Ib Tub A基因的特异条带,能够进行后续实验分析,其中华越洋试剂盒提取法操作更加快捷和方便。另外三种提取方法都存在一些弊端,所提取RNA质量略差,不能达到后续实验的要求。增加去色素环节可以有效去除色素,三个不同色素差异品种的提取结果较为一致。展开更多
