在siRNA序列设计时,将潜在的序列用BLAST进行同源序列搜索时,出来的结果好象总是存在和其它编码序列同源的序列,郁闷!是不是可以只看E值?还是只看score?这个问题好菜! 我的目的序列是Human P-glycoprotein (MDR1)中的一个片断,请问出现以下的结果如何判断这个目的序列与其它编码序列不是同源的序列?下面是BLAST的结果: Score ESequences producing significant alignm ...

我想把目的基因连接到载体上,有几个问题想请教斑竹和各位战友:1、限制性内切酶的选择:我查看论坛说选择酶切位点需要考虑酶切位点在载体上的距离、酶切温度与连接效率、价格、使用频率等等。最后我综合价格、温度、Buffer选定XbaI和EcoRI,打算购买宝生的酶,相应的Buffer用附带的10×M Buffer。不知道我选择的酶切位点合适不合适呢?2、引物设计:引物结构为:保护碱基+酶切位点+目的基因末端上游引物5’-CCG TCT ...

RNAi从发现到现在,短短几年时间,已经由一种生理现象发展为生物医学研究的重要手段和具有很大潜力的治疗手段。目前,哺乳动物细胞的RNAi主要依赖于长19~21bp,3‘端悬挂2nt的对称的RNA双链,即短干扰RNA(siRNA)。这里,作者报道了一种长15bp、3’和5‘端分别悬挂3nt的反义核苷酸的非对称的RNA双链,即非对称干扰RNA(aiRNA),可以有效诱导哺乳动物细胞RNAi的发生。研究表明aiRNA诱导的 ...
