| 摘 要： | 实时荧光定量RT-PCR是检测低丰度mRNA的敏感方法,也是精确定量RNA拷贝数的有效方法,它的出现使得在少量细胞中定量基因的表达量,在小量基因组中分析基因突变和等位基因缺失成为可能。为了使这种检测技术更加稳定可靠,就必须在检测步骤的每一环节做到精确无误,而总mRNA的提取质量就显得十分重要。研究选择了牛MⅡ期的卵母细胞作为研究对象,对不同保存方法进行了检测和比较,结果显示,-196℃液氮和-80℃冰箱保存24 h的卵母细胞,总RNA品质并未明显下降;在-20℃或-80℃环境中长时间保存cDNA模板都会造成模板品质的下降。

| Abstract: | Real-time polymerase chain reaction(PCR) in combination with reverse transcription(RT) provides a powerful tool for accurate quantification of RNA copy numbers and has opened the way to the study of subtle modulations of gene expression in small numbers of cells,as well as small-scale genetic analyses aimed at establishing chromosome numbers,the presence of mutations,or allele dropout.The reliability of these measurements,however,depends on the accuracy of each step.Effects of different methods on preservin... |
