In this chapter, we describe a stepwise protocol of microinjection. Using this method, antisense morpholinos, CRISPR-Cas9 ribonucleoprotein complexes, capped mRNA, and DNA can be delivered into fertilized zebrafish eggs to manipulate gene expression during development. This protocol can also be adapted for microinjection in other fish and amphibian species.

D000094704	RNA, Guide, CRISPR-Cas Systems	A component of CRISPR-Cas SYSTEMS. Cas endodeoxyribonucleases assemble with a guide RNA complex, a hybrid of CRISPR RNA (crRNA) and transactivating crRNA (tracrRNA) molecules, to form an active complex that cleaves DNA. crRNA and tracrRNA can be synthetically fused into a single RNA molecule, namely single guide RNA. Synthetic sgRNA is used with CRISPR-Cas SYSTEMS for targeted GENE EDITING.
