Abstract

Plasmid-based CRISPR knock-in is a streamlined, scalable, and versatile approach for generating fluorescent protein tags in (Dickinson . 2015; Schwartz and Jorgensen 2016). However, compared to more recent protocols that utilize commercially available Cas9/RNP products and linear DNA repair templates (Dokshin . 2018; Ghanta and Mello 2020), the cloning required for plasmid-based protocols has been cited as a drawback of this knock-in approach. Using thorough quantitative assessment, we have found that cloning efficiency can reproducibly reach 90% for the plasmids of the self-excising cassette (SEC) selection method, essentially resolving cloning as a burden for plasmid-based CRISPR knock-in.

摘要

基于质粒的CRISPR敲入是一种用于在(Dickinson. 2015;Schwartz和Jorgensen 2016)中生成荧光蛋白标签的简化、可扩展且通用的方法。然而,与使用市售Cas9/RNP产品和线性DNA修复模板的更新协议(Dokshin. 2018;Ghanta和Mello 2020)相比,基于质粒的协议所需的克隆被认为是这种敲入方法的一个缺点。通过全面的定量评估,我们发现自切割盒(SEC)选择方法的质粒克隆效率可重复达到90%,基本解决了克隆作为基于质粒的CRISPR敲入负担的问题。
