从水稻种胚中提取RNA的新方法 总被引:16,自引:0,他引:16
介绍了一种全新、简单的提取水稻种胚RNA的CTAB-LiCl提取法,可在不用液氮的室温下有效地排除剥取的种胚中大量带有的多糖和本身脂质的干扰,所得RNA样品经紫外分光光度计和琼脂糖凝胶电泳分析证明具有较高的纯度和完整性,并可进一步满足RT-PCR和Northern 印迹的实验需要,适用于富含多糖和脂质的植物组织RNA的提取。
Abstract:A novel and simple CTAB-LiCl-based extraction method for high-quality and total RNA of rice embryo samples is developed.This method can efficiently eliminate the interference of polysaccharide and lipids rich in rice(Oryza sativa L.)embryo obtained under room temperature without using liquid nitrogen.The results of ultraviolet spectrophotometer and agarose gel electrophoresis analysis show that the obtained RNA has no obvious degradation and a good purity sufficient for further RT-PCR and RNA gel blotting.Therefore,it is also especially useful for the RNA extraction of plant material plenty of polysaccharide and lipids. 相似文献

一种简单、快速筛选水稻种胚脂氧合酶-3缺失体的新方法 总被引:4,自引:0,他引:4
根据水稻种胚脂氧合酶-3(LOX-3)催化产物的氧化特性,结合脂氧合酶的专一性抑制剂——去甲二氢愈创木酸,建立了筛选水稻种胚脂氧合酶-3缺失体的I2-KI比色法,并探讨其最佳实验条件.与常用的单克隆抗体筛选技术相比,该方法具有准确、简单且成本低的特点,可以进一步用于耐储藏水稻的育种研究. 相似文献
