Dissection du complexe œil-cerveau à partir de pupes de mouches : une méthode pour isoler le tissu rétinien

Executive Industry Relevance

Isolation of the Drosophila eye-brain complex enables mechanistic de-risking in early target validation by providing a disease-relevant system for studying neural development and visual processing pathways. This method supports phenotypic screening and assay development by yielding high-quality tissue compatible with immunostaining, western analysis, and RNA isolation. The protocol enhances predictive confidence in target identification through reproducible dissection of a genetically tractable model system.
