Immunocolorazione a montaggio intero e conteggio automatico delle cellule gangliari retiniche di topo

Overview

This study outlines a protocol for isolating the whole-mount mouse retina and conducting immunostaining to label retinal ganglion cells (RGCs). Utilizing an AI-based software for automated counting allows for a rapid and accurate quantification of RGCs, facilitating the study of conditions like glaucoma.
