CRISPR/Cas9系统介导的基因定点编辑技术，可实现由sgRNA指导Cas9核酸酶对靶基因的DNA进行定点修饰，其特异性依赖于sgRNA与靶标位点通过碱基互补配对，并且靶标位点必须含有PAM序列（NGG）。
尽快目前有很多sgRNA设计软件，但实现高通量快速全基因组设计sgRNA的程序不多，宇玫博开发的拥有自主知识产权“高通量sgRNA文库设计软件”，该软件能针对任意物种，任意来源的序列设计sgRNA，可用于构建sgRNA表达载体用于基因组编辑实验，同时可用于设计sgRNA文库。
服务内容：
1， 高通量sgRNA文库设计；
2， sgRNA文库探针Oligo Pools合成；
每个pool可以提供12,000 到90,000 不同的oligo序列.
