| Summary: | Summary: Since its first application for site-directed mutagenesis, the CRISPR-Cas9 system has revolutionized genome engineering. Here, we present a validated workflow for the generation of targeted genomic deletions in zebrafish, including the design, cloning, and synthesis of single-guide RNAs and Cas9 mRNA, followed by microinjection in zebrafish embryos and subsequent genotype screening for the establishment of a mutant line. The versatility and efficiency of this pipeline makes the generation of zebrafish models a widely used approach in functional genetics.For complete details on the use and execution of this protocol, please refer to Amorim et al. (2020).
