Powerful software designed for CRISPR makes it quick and easy to find sites, design guide RNAs and analyze your editing results
The gRNA:The role of the gRNA is to target Cas9 cleavage. Depending on the specifics of your experiment, you may want to use an online gRNA design tool that will search a relatively large sequence for candidate gRNAs and score them. If however, your experiment is more constrained to a sm...
gRNA设计是CRISPR基因编辑的核心,KO比较简单,可选择的gRNA很多,而对于需要指定locus的编辑,如CRISPRa, CRISPRi, base editing等,可选择的就很少。 可以选择现成的工具:https://portals.broadinstitute.org/gppx/crispick/public CRISPR衍生品很多,甚至可以编辑表观标记,EP300 dcas9 Epigenome editing by a CRISPR/Ca...
GenCRISPR gRNA design tool is a free online tool to design individual gRNA and gRNA library. It employs a newly-developed algorithm which integrates the design instructions from the latest progress and expertise. With GenCRISPR gRNA design tool, you can design gRNAs target either 1 gene or multi...

Clustered regularly interspaced short palindromic repeats (CRISPR) technology has been adapted for gene editing to serve as an efficient, rapid, and cost-effective tool. To fulfill CRISPR experiment's goals, two components are important: an endonuclease and a gRNA. The most commonly used ...
为了帮助科学家设计 gRNA,学术界已经开发了超过 30 种基于网页的 gRNA 设计工具。 Nature Method编辑着重介绍了由来自哈佛大学与 MIT 联合成立的博德研究所学者 John G. Doench 于 2020 年 4 月 13 年发表在Nature Biotechnology的综...
1. gRNA设计：选择目标基因的DNA序列，设计与其互补的20 bp的gRNA，同时考虑到PAM序列（通常为NGG）。使用在线工具（如CRISPR Design Tool）可以帮助寻找最佳靶点。2. 构建表达载体：将gRNA序列克隆到gRNA表达载体中，通常还需要Cas9表达载体或将gRNA和Cas9基因融合到同一个质粒上。3. 细胞转染或转导：将gRNA和Cas9...
将痕量的核酸模板扩增到可以检出的水平；单分子荧光检测技术(SM@RT)，集恒温扩增与荧光信号检测于一体，可实现扩增过程的实时检测；核酸快速释放技术，为实验节省更多的时间。CRISPR-ERA，基因编辑与调控的gRNA设计，ERA核酸扩增体系，都是在基因领域的重要组成部分，相信两者在后期基因领域的运用中会也来越广泛。
