Product Name TRIpure Reagent
Introduction： TRIpure 是广谱型总RNA提取试剂。实验操作快速方便，颜色鲜明，便于分层。本试剂适用范围广泛，可以从动物组织、 植物材料、 各种微生物及培养细胞等样品中提取总RNA。 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。样品在TRIpure中被充分裂解的同时能够最大限度地保证RNA的完整性。在加入氯仿离心后，溶液会分成三层：上层无色水相、中间层和下层红色有机相，RNA 分布在上清层中。收集上清层后，经异丙醇沉淀便可以回收得到总RNA。提取的总RNA完整性好，无蛋白和DNA污染，可用于各种分子生物学常规实验，如RT-PCR、Real-time RT-PCR、Northern blot、Dot Blot、体外翻译等。 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7kb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。注意如果是普通琼脂糖凝胶电泳，28S的位置大约在2kb，18S大约在1kb的位置，不同浓度的凝胶位置变化较大。
