Geliştirici Tabanlı İfade Yapılarının AAV Dağıtımı In Vivo in Mouse Brain

Overview

This study presents a novel rAAV-based transient enhancer-reporter assay for in vivo use in the mouse brain to visualize enhancer-driven gene expression. The protocol enables researchers to quickly assess not only if an enhancer can drive expression but also where it can do so within specific brain regions.
