Expression of mGSH carrier proteins in mouse RPE/Choroid (A) and whole retina (B). Mitochondria was isolated as described earlier [97], and the specificity of expression in mitochondria is illustrated with COX IV as a mitochondria specific marker in A. Immunofluorescence staining of OGC (green) and DIC (green) in retinal layers is shown in B. Mito: mitochondria, Cyto: cytosol, COX IV: cytochrome c oxidase subunit 4, Reproduced from [97] and is licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License. Blue: nuclear stain, DAPI. OS—outer segment, IS—inner segment, ON—outer nuclear layer.
