Kıvılcım Susturma: CRISPR/Cas9 Zayıf Elektrikli Balıklarda Genom Düzenleme

Overview

This study outlines a protocol to produce and rear CRISPR/Cas9 genome knockout electric fish, specifically focusing on weakly electric fish from the Gymnotiformes and Mormyridae families. The detailed methods for molecular biology, breeding, and husbandry are provided, enabling researchers to generate mutant F0 larvae for studying gene function.

Key Study Components

Research Area
