Generating CRISPR Alleles in Drosophila.

ABSTRACT

CRISPR gene editing is a versatile and efficient approach for generating a wide variety of genetic reagents in flies. This unparalleled ability to manipulate the genome has revolutionized neuroscience, allowing Drosophila neurobiologists to readily generate new alleles to probe gene function, investigate the functional consequences of disease-associated variants, tag endogenous proteins to follow their dynamic localization in neurons and glia, and much more. Here, we provide a comprehensive protocol for generating heritable mutations in Drosophila We particularly focus on design considerations and tips for avoiding common errors to maximize the likelihood of successful gene editing.
