Immunohistochemistry using mouse retinal cryosections is a routine assay used in vision research. However, retinal tissues are fragile, and it is difficult to obtain an ideal retinal cryosection. Here, we developed a modified method for preparing retinal cryosection. Super Glue was applied on the surface of the sclera before the cornea and the lens are removed from either the unfixed or PFA-fixed mouse eyeballs. The new methods largely prevented retinal detachment in mouse retinal cryosections. Immunostaining of retinal cryosections derived from PFA-fixed mouse eyes using rod and cone markers yielded high-quality immunofluorescent images. Immunolabeling of retinal cryosections obtained from unfixed mouse eyes using a cilium-specific marker had improved orientations of photoreceptor connecting cilia. This new method substantially improves the morphology and immunostaining results of fixed and unfixed mouse eyes.
