Addgene Comments
Using FLEX vectors in vivo: LoxP sites in FLEX plasmids are known to recombine during DNA amplification and viral vector production, which may result in a minority of Cre-activated (i.e., "flipped") viral vectors. Addgene has measured this occurs in 0.01-0.03% of viral vectors in our typical production protocol. This can lead to a small number of cells exhibiting Cre-independent transgene expression in vivo. To address this, we recommend titrating to find the optimal AAV dosage required for Cre-dependent transgene expression and function in vivo. This may include reducing the viral vector dosage in order to reduce the likelihood of Cre-independent expression.

1.破碎和裂解植物细胞壁。
2.抑制rna酶
3.去除植物多糖和多酚。树脂 淀粉和纤维材料。
4.去除许多高等植物组织尤其是成熟组织能产生某些水溶性的次级代谢产物，这些次级代谢产物很容易与RNA结合并与RNA共同被抽提出来而阻碍具有生物活性的RNA分离。
除了干扰RNA分离之外，植物多糖和多酚及次级代谢产物还能明显抑制下游RNA反应如转录和PCR.
TRIZOL的主要成分是苯酚。苯酚的主要作用是裂解细胞，使细胞中的蛋白，核酸物质解聚得到释放。苯酚虽可有效地变性蛋白质，但不能完全抑制RNA酶活性，因此TRIzol中还加入了8－羟基喹啉、异硫氰酸胍、β-巯基乙醇等来抑制内源和外源RNase（RNA酶）。
TRIZOL是从细胞和组织中提取总RNA的即用型试剂，在样品裂解或匀浆过程中，TRIZOL 能保持RNA完整性。加入氯仿后，溶液分为水相和有机相，RNA在水相中。取出水相，用异丙醇可沉淀回收RNA。
※0.1%的8－羟基喹啉可以抑制RNase，与氯仿联合使用可增强抑制作用。
※异硫氰酸胍属于解偶剂，是一类强力的蛋白质变性剂，可溶解蛋白质并使蛋白质二级结构消失，导致细胞结构降解，核蛋白迅速与核酸分离。
※β-巯基乙醇的主要作用是破坏RNase蛋白质中的二硫键。
TRIZOL是一种新型总RNA抽提试剂，可以直接从细胞或组织中提取总RNA。其含有苯酚、异硫氰酸胍等物质，能迅速破碎细胞并抑制细胞释放出的核酸酶。TRIZOL在破碎和溶解细胞时能保持RNA的完整性，因此对纯化RNA及标准化RNA的生产十分有用。
基本特点
Trizol试剂可以快速提取人、动物、植物、细菌不同组织的总RNA，该方法对少量的组织（50-100 mg）和细胞（5×106）以及大量的组织（≥1 g）和细胞（>107）均有较好的分离效果。TRIZOL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。TRIZOL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。并且利用DNA、RNA和蛋白质在不同溶液中的溶解性质，可以通过分层分别将不同层中的RNA（上层）、DNA（中层）、蛋白质（下层）分离纯化出来，效率极好。
Trizol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RNA条带位于~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

求助：最近要提取血浆中的RNA，不知道用哪种试剂好，查了好多资料，有用Trizol，TrizolLS，RNAisoBlood和天根。但我从没做过，求各位大神给点意见。提取的RNA用于qPCR。
总RNA提取试剂盒（TRIzol法）
RIpure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。
