Nanopore测序制备的文库类型有三种:2D文库、1D文库和1D2文库,但目前应用最多的是1D文库。 1D文库构建是基因组DNA经过片段化、末端修复后,在片段两端加上带有Motor蛋白(动力蛋白)的测序接头和Tether蛋白等,使得在测序时DNA正反链单独测序。 2D文库同1D文库类似,只是将文库一侧用发夹接头将DNA正反链相连,使得在测序时...

We find that our banded 2D beam search improves the median accuracy from 87.6% for single reads to 93.2% for 1D2 read pairs (Fig. 2), nearly halving the error rate of our PoreOverNet basecaller. Our software can readily be adapted to work with the output of other neural network base...

有两种芯片R9.4.1和R5.5.1,9.4适用于1D测序(单链),9.5适用于1D2测序(双链)。原来有一个2D的测序方法,据说是与PacBio有专利矛盾,现在已经不用了。三代测序的错误率都比较高,10%-20%,上半年北京的Nanopore大会上报告其准确性提升到了93%。最新的R10芯片(在通道蛋白里有两个reader,可以用来校正信息,提高测序...
Nanopore有三种建库方式,主要在接头上的差异,根据加入不同的接头可以分为1D、2D和1D2文库。1D文库加入引导接头(Leading Adaptor),2D既有引导接头,还有连接双链DNA分子的发夹接头(Hairpin Adaptor),1D2测序先加入1D2接头,再连接引导接头。当模板链完成测序后,互补链的马达蛋白被捕获进行互补链测序(图4)。从目前应...
到达发夹接头后,另一种蛋白质,即发夹蛋白质,允许互补的DNA链以类似的方式穿过纳米孔)这是一种2D的文库,实际上后来ONT感觉上逐渐淘汰了这种方案。实际上还有1D和1D2两种,区别就是 PacBio和NanoPore两种三代测序仪的比较 分子。其测序原理通俗解释,就是想办法让单链DNA通过这个纳米孔。但是,纳米孔两侧有一个记录...
