CRISPR-associate (CRISPR/Cas), has been adapted as a powerful gene editing tool and got a broad application in genome research field due to its ease of use and cost-effectiveness. The performance of CRISPR/Cas relies on well-designed single-guide RNA (sgRNA), so a lot...
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表...
Design When doing your first editing experiment, we recommend performing this positive control first, or in parallel. Order primers for gRNA synthesis and for GeneArt genomic cleavage detection assay using...
the dual guide RNAs/Cas9 system has a great deal of advantages, such as higher efficiencies, easy to screen the positive clones, much more optional for guide RNA design ( you can design two guide RNAs in the
Hence, we present an overview of the past and the most recent guide RNA web-based design tools, highlighting the evolution of their computational architecture and gRNA characteristics over the years. Our study explains computational approaches that use machine learning techniques, neural net...
和ZFN，TALEN一样，CRISPR-Cas也是通过激活DSB的模式来达到基因标记的目的。CRISPR RNA (crRNA) array，编码gRNA，再加上tracrRNA，则可达到定位+编辑的功能 gRNA用于引导，tracrRNA用于结合靶点。所以，人们就把crRNA和tracrRNA合在一起，成为了single-guide RNA，即sgRNA，而通过修改tracrRNA的序列，在理论...
sgRNA design and generation of lentiviral constructs sgRNAs were designed using the online Benchling CRISPR gRNA Design tool (http://www.benchling.com). The sgRNAs chosen were based on a high specificity rank and a low potential off-target score53. The parental Streptococcus pyogenes Cas9 expressi...

从体外实验来看,Atp2b2-mut1对Obl等位基因的编辑效率最高,而对WT等位基因的编辑效率不最高,因此选择gRNA Atp2b2-mut1进行体内研究。为探究其他效率较低的sgRNAs挽救OHC功能和听力的能力,作者注射Atp2b2-mut2 到4周 Atp2b2Obl/+小鼠,与对侧未注射耳相比,发现注射Atp2b2-mut2 Atp2b2Obl/+耳的DPOAE或ABR阈值没...
