RNAiprotocol
siRNA protocolsOur current strategy with siRNA is to synthesis relatively small amounts enzymatically and use these to test for efficiency by western blotting. This allows us to test several candidate siRNAs quite cheaply. The yields are good enough for reasonable amounts of experimental work, but for larger use we get successful siRNAs synthesised chemically by Dharmacon.DesignThe Tuschl lab siRNA us......阅读全文

RNAi的功能
1.高通量的研究基因功能在后基因组时代，需要大规模高通量的研究基因的功能，由于RNAi能高效特异的阻断基因的表达，因而RNAi成为研究基因功能的很好的工具。研究者将线虫三号染色体上2232个基因对应的dsRNA合成出来，并注射到线虫性腺内，然后观察子代细胞分裂时出现的异常表型，结果发现了133个基因
RNAi相关术语
1.RNAi ：（RNA interference）RNA干扰一些小的双链RNA可以高效、特异的阻断体内特定基因表达，促使mRNA降解，诱使细胞表现出特定基因缺失的表型，称为RNA干扰（RNA interference，RNAi ，也译作RNA干预或者干涉）。它也是体内抵御外在感染的一种重要保护机制
RNAi的特征
①RNAi是转录后水平的基因沉默机制；②RNAi具有很高的特异性，只降解与之序列相应的单个内源基因的mRNA；③RNAi抑制基因表达具有很高的效率，表型可以达到缺失突变体表型的程度，而且相对很少量的dsRNA分子（数量远远少于内源mRNA的数量）就能完全抑制相应基因的表达，是以催化放大的方式进行的；
