Expression profile of IFT43 in mouse and human retina. Immunostaining of retinal sections of a 6-month-old mouse and a 57-year-old human donor revealed IFT43 localized predominantly to the photoreceptor region of the retina (A and C). IFT43 was stained and observed in the red channel and indicated by the red arrow. Rhodopsin (green) and S-Opsin (white) are stained with specific antibodies and nuclei are stained with DAPI (blue). Immunostaining of mouse and human retinal sections with secondary antibodies alone did not reveal positive staining (B and D). RPE, Retinal pigment epithelium; OS, Outer Segments; ONL, Outer Nuclear Layer; OPL, Outer Plexiform Layer; INL, Inner nuclear layer; IPL, Inner Plexiform Layer; GC, Ganglion Cell Layer.
