Geração de camundongos knockout específicos para gordura marrom usando um sistema combinado de RNA guia único Cre-LoxP, CRISPR-Cas9 e vírus adenoassociado

Overview

This protocol describes a method to generate brown adipose tissue (BAT)-specific knockout mice using a combination of Cre-LoxP, CRISPR-Cas9, and adeno-associated virus (AAV) single-guide RNA techniques. By utilizing these methods, researchers can quickly create tissue-specific knockouts without the need for selective breeding.
