The Guide-it CRISPR/Cas9 systems are kits for the cloning and expression of single guide RNAs (sgRNAs) for mammalian genome editing using CRISPR/Cas9 technology. The vectors in these systems simultaneously express Cas9 nuclease, a target-specific sgRNA, and an exceptionally bright fluorescent protein for monitoring transfection efficiency and/or for further enriching/isolating transfected cells by flow cytometry (ZsGreen1 and tdTomato versions are available).

Generating a plasmid that expresses a sequence-specific sgRNA with this system is simple: a pair of user-provided oligos corresponding to the target genomic sequence of interest are annealed to form a duplex, and the duplexed oligos are inserted into the pre-linearized vector using the included high-efficiency ligation mix. The kit also includes Stellar Competent Cells to ensure high-efficiency transformation.

现在已经把bac克隆的质粒DNA提取出来了，但是在标记探针前，有以下几个疑问：
1：提取出的质粒DNA是否需要通过测序等方法进行验证该克隆的准确性？
2：是否需要把bac克隆的DNA从载体上酶切下来？如果酶切，UCSC数据库中提供的两侧序列末端的酶切位点就是吗？如果不用酶切，那载体片断在探针标记时会不会一同标记上从而影响后续试验结果？
3：在探针标记前，酶切或不酶切得到的bac克隆DNA是否需要进一步纯化？用普通的琼脂糖电泳切胶回收纯化就可以吗？那所用的切胶回收试剂盒应该是哪种的呀？
4：像我这种自己标记好探针，在作fish时，有现成的试剂盒吗？
第一次做fish，有好多不是很清楚的地方，查阅大量文献中也只是提供其中几个关键步骤，希望有经验的朋友提供宝贵意见，给与指导。
非常感谢！！！
大家好，我最近在克隆一个基因的全长序列，用的是cDS，之前的引物在NCBI上Blast,是特异引物，一开始没有条带，通过不断的试程序，重提RNA等，出现条带了，大小也对，结果测序不是我的基因，然后重新换引物，现在的情况是，51度有我的条带，但是有很多杂带，升高退火温度后，以及减少循环后，啥也没有了，求大神指点。
