Overview
This protocol outlines the dissection and immunohistochemistry of Drosophila retinas at three developmental stages: larval, pupil, and adult. It emphasizes the visualization of proteins expressed during retina development, allowing for the study of photoreceptor differentiation at the single-cell level.
Key Study Components
