Conclusion:

Passed. Presence of specific signal in the RPE cell layer was considered as indication of specific immunoreactivity using the anti-RDH5 antibody ABIN7254060.

Validation Images

Retinal sections from the wild-type (B6 albino) mice immunostained with anti-RDH5 antibody ABIN7254060. DAPI staining shows localization of the inner (INL) and outer (ONL) nuclear layer of the mouse retina. Cralbp (Rlbp1) co-staining was used to visualize RPE and Müller glia cells in the retina. Presence of specific signal in the RPE cell layer confirms specific immunoreactivity.

Full Protocol:

• Collect eyes from mice and fix with paraformaldehyde 4% (Electron Microscopy Sciences, 15710) in 1x PBS for 30 min at RT.
• Cryoprotection with sucrose series:
• • Wash in 10% sucrose in 1x PBS.
  • Immerse in 10% sucrose in 1x PBS for 30 min at RT.
  • Wash in 20% sucrose in 1x PBS.
  • Immerse in 20% sucrose in 1x PBS for 30 min RT.
  • Wash in 30% sucrose in 1x PBS.
  • 30% sucrose ON at 4°C.
• Embed eyes in OCT compound (Tissue-Tek O.C.T. Compound, 4583).
• Cut retinal sections at a thickness of 12 μm on a cryostat.
• Air dry sections for 15 min at RT, store at -80°C until use.
• Bring sections to RT and rehydrate in 1x PBS for 1 h.
• Incubate sections in blocking buffer (1x PBS, 3% BSA (Sigma-Aldrich, A7030), 3% Donkey serum (Sigma-Aldrich, S30-100ML), 0.1% Triton X-100 (Sigma-Aldrich, X100-500ML)) for 1 h at RT.
• Incubate sections with primary rabbit anti-RDH5 antibody (antibodies-online, ABIN7254060, lot SG5433) diluted 1:50 in blocking buffer ON at RT. Include a no primary antibody negative controls. Additionally, counterstaing with primary mouse anti-CRALBP antibody (Thermo Fisher Scientific, MA1-813).
• Rinse sections 3 times with 1x PBS, 0.1% Triton X100. Keep negative controls in a separate container.
• Incubate sections with secondary AF647-conjugated donkey anti-rabbit antibody (Abcam, Ab150075) or AF488-conjugated donkey anti-mouse antibody (Thermo Fisher Scientific, A32766) diluted 1:500 in blocking buffer for 1 h at RT.
• Rinse sections once with 1x PBS, 0.1% Triton X-100 for 5 min at RT.
• Incubate sections in 1x DAPI (Thermo Fisher Scientific, 62248) in 1x PBS, 0.1% Triton X-100 for 15 min at RT.
• Rinse sections 3x with 1x PBS, 0.1% Triton X-100 for 5 min at RT.
• Mount sections in VECTASHIELD® HardSet™ Antifade Mounting Medium (Vector Laboratories, H-1400) mounting medium.
• Acquire images with a fluorescence microscope and appropriate filter settings.For the validation purposes Keyence BZ-X800E fluorescence microscope was used with following filters: BZ-X DAPI for DAPI, BZ-X GFP for AF488, BZ-X Cy5 for AF647. Images were taken at 10x and 40x magnification.

Notes:

• Experiment involved validation of the specificity of 4 antibodies against different Rdh proteins: Rdh5 (ABIN7254060), Rdh10 (ABIN7118460), Rdh11 (ABIN966957), and Rdh12 (ABIN7167836). All 4 proteins are important for eye function and highly expressed in neural retina and/or RPE. Validation is based on comparison of each staining with known pattern of expression in the mouse retina. For review highlighting each Rdh localization see PMID20801113.

• To aid orientation in the cell layers anti-Cralbp counterstain was included in the staining (Thermo MA1-813). Cralbp (Rlbp1) is highly expressed in RPE and Müller glia cells in mouse retina.

Sujet: This gene encodes an enzyme belonging to the short-chain dehydrogenases/reductases (SDR) family. This retinol dehydrogenase functions to catalyze the final step in the biosynthesis of 11-cis retinaldehyde, which is the universal chromophore of visual pigments. Mutations in this gene cause autosomal recessive fundus albipunctatus, a rare form of night blindness that is characterized by a delay in the regeneration of cone and rod photopigments. Alternative splicing results in multiple transcript variants. Read-through transcription also exists between this gene and the neighboring upstream BLOC1S1 (biogenesis of lysosomal organelles complex-1, subunit 1) gene.
