Methanol-Based Whole-Mount Preparation for the Investigation of Retinal Ganglion Cells

Overview

This study presents a modified workflow for isolation and long-term storage of retinal tissue samples, specifically designed for investigating retinal ganglion cells (RGCs). Given the fragility of retinas, the developed method facilitates whole-mount preparations without the need for immediate immunostaining, allowing for better preservation and future analyses.
