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
1995年，康乃尔大学的Su Guo博士在试图阻断秀丽新小杆线虫（C. elegans）中的par-1基因时，发现了一个意想不到的现象。她们本是利用反义RNA技术特异性地阻断上述基因的表达，而同时在对照实验中给线虫注射正义RNA（sense RNA）以期观察到基因表达的增强。但得到的结果是二者都同样

RNAi总结
RNA干涉（RNAi）是指双链RNA分子使基因表达沉寂的现象，是在线虫中发现的，在 1998年的一篇Nature论文中被公诸于众。过去几年中，科研工作者已明确转录后基因沉默现象普遍存在于动、植物中，在机体防御病毒入侵和转座子沉默效应中起着重要作用。近年来的研究表明，将与mRNA对应的正义RNA和反义
