 产品介绍
TRIpure 试剂是直接从细胞或组织中提取总RNA的试剂。它在破碎和溶解细胞时能保持RNA的完整性。加入氯仿后离心,样品分成水样层和有机层。RNA存在于水样层中。收集上面的的水样层后,RNA可以通过异丙醇沉淀来还原。在除去水样层后,样品中的DNA和蛋白也能相继以沉淀的方式还原。乙醇沉淀能析出中间层的DNA,在有机层中加入异丙醇能沉淀出蛋白。共纯化DNA对于样品间标准化RNA的产量十分有用。
无论是人、动物、植物还是细菌组织,该方法对少量的组织(50-100mg)和细胞(5×106)以及大量的组织(≥1g)和细胞(>107)均有较好的分离效果。TRIpure 试剂操作上的简单性允许同时处理多个的样品。所有的操作可以在一小时内完成。TRIpure抽提的总RNA能够避免DNA和蛋白的污染。故而能够作RNA印迹分析、斑点杂交、poly(A)+选择、体外翻译、RNA酶保护分析和分子克隆。如果是用于PCR,当两条引物位于单一外显子内时,建议用扩增级的DNase I来处理抽提的总RNA。
TRIpure 试剂能促进不同种属不同分子量大小的多种RNA的析出。例如,从大鼠肝脏抽提的RNA琼脂糖凝胶电泳并用溴化乙啶染色,可见许多介于7 kb和15 kb之间不连续的高分子量条带(mRNA和hnRNA成分),两条优势核糖体~5 kb (28S)和~2 kb(18S),低分子量RNA介于0.1和0.3 kb之间 (tRNA, 5S)。当抽提的RNA用TE稀释时其A260/A280比值≥1.8。

The TRIpure Reagent RNA Purification provides a simple, reliable, and rapid method for isolating high–quality total RNA from a wide variety of samples, including animal and plant cells and tissue, bacteria, and yeast. The kit utilizes the strong lysis capability of TRIpure Reagent. TRIpure Reagent maintains the integrity of the RNA, while disrupting cells and dissolving cell components. Addition of chloroform followed by centrifugation, separates the solution into an aqueous phase and an organic phase. RNA remains exclusively in the aqueous phase. After transfer of the aqueous phase, the RNA is recovered by precipitation with isopropyl alcohol. After removal of the aqueous phase, the DNA and proteins in the sample can be recovered by sequential precipitation. Precipitation with ethanol yields DNA from the interphase, and an additional precipitation with isopropyl alcohol yields proteins from the organic phase. Copurification of the DNA may be useful for normalizing RNA yields from sample to sample. Total RNA isolated by TRIpure Reagent is free of protein and DNA contamination. It can be used for Northern blot analysis, dot blot hybridization, poly (A)+ selection, in vitro translation, RNase protection assay, and molecular cloning.
