    • IHC image of CSB-PA005941DSR1HU diluted at 1:66 and staining in paraffin-embedded human eye tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.
    • Immunofluorescence staining of Hela cells with CSB-PA005941DSR1HU at 1:22, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).

    1. Several Crb mutant proteins accumulated abnormally in the rhabdomere and affected rhodopsin trafficking, suggesting that abnormal rhodopsin physiology contributes to Crb/CRB1-associated retinal degeneration. PMID: 28515229
    2. Novel compound heterozygous mutations found in CRB1 were identified in a Chinese pedigree with Autosomal-recessive retinitis pigmentosa using targeted-capture next generation sequencing. PMID: 27806333
    3. Retinal capillaritis, vitritis, and cystoid macular edema could be inflammatory features of CRB1 retinal dystrophy in our young patient. PMID: 28129017
    4. In summary, mutations in CRB1 need to be considered as a potential cause of isolated maculopathy, particularly in cases where the central macular atrophy is associated with paracentral macular thickening and loss of normal lamination on OCT. PMID: 27096895
    5. The traditional village therapy may have compromised retinal venous outflow and/or provoked a Valsalva phenomenon, leading to the bilateral retinal hemorrhages. The fact that this occurred bilaterally and in both sisters supports the concept of relative vessel wall incompetence as part of CRB1-related retinopathy. PMID: 27007588
