Application Notes
For Western blot, this antibody has been validated in lysates of bovine RPE membrane and COS7 cells transfected with human RPE65, and in both samples, the antibody recognized a band at ~65 kDa, representing RPE65 protein. Note:- Hamel et al. have reported that in cultured bovine RPE cells, the levels of RPE65 are undetectable in WB after day 14, however, the mRNA levels are detectable by Northern for at least 7 weeks (PMID: 8340400). The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors. This antibody is CyTOF ready. Use in Immunoprecipitation reported by customer review. Use in In vivo reported in scientific literature (PMID:32173468).

Background

RPE65 (retinal pigment epithelium-specific 65 kDa protein) was first described in 1991 and is a key isomerase in RPE that is largely localized to the smooth endoplasmic reticulum (1,2). The RPE65 gene is located on chromosome 1p31 and the protein is synthesized as 533 amino acids in length with a theoretical molecular weight of 61 kDa, although appearing near 65 kDa in SDS-PAGE (1,3). RPE65 serves an important enzymatic function in the visual cycle in converting all-trans-retinyl esters into 11-cis-retinal (1-6). In the visual cycle, light activates rhodopsin and other visual pigments in the photoreceptor cells (rods and cones), eventually generating all-trans-retinol which is transported to the RPE and converted to the vitamin A-derived chromophore 11-cis-rentinal via RPE65 and is then diffused back to the photoreceptor to continue the cycle (1-6). Although it is still unclear, some studies have suggested that S-palmitoylation post-translational modification of RPE65 is responsible for the stability and anchoring to the RPE membrane and therefore functioning enzymatic activity (1,2).

Given its essential role in the vision cycle, it is understandable that mutations in RPE65 are associated with a variety of inherited retinal dystrophies (1, 3-6). Leber Congenital Amaurosis (LCA) and retinitis pigmentosa (RP) are two of the most common retinal dystrophies associated with bi-allelic RPE65 gene mutations (5,6). In 2017 the FDA approved an in vivo gene therapy for treatment of RPE65-associated diseases (5,6). The drug Voretigene Neparvovec, also called Luxturna, is delivered sub-retinally and transduces RPE cells with cDNA encoding for normal RPE65 to help restore vision (5,6). There are several promising completed and ongoing clinical trials for treating RPE65-associated diseases using gene replacement therapy (5).

Comments

CommentsWe applied this antibody to endogenous RPE65 from bovine RPE cell extracts and human RPE65 overexpressed in 293T cells. In both cases it produced robust immunoprecipitation and good western blot signal. Four stars because it does recognize a relatively strong nonspecific band around 40 kD in 293T cell lysates.

FAQs for RPE65 Antibody (NB100-355). (Showing 1 - 5 of 5 FAQs).

  1. I have one question regarding the immunoblot of the RPE65 I always got two bands in positive control. I am not able to understand why. Please clarify my doubt. I am unsing Novus RPE65 antibody.
    • RPE65 is subject to several different post-translational modifications that influence its apparent band size in an SDS-PAGE gel. Please see UniProt to learn more. The doublet you are seeing (which we also observe) most likely reflects an unmodified and a modified version of the protein. I hope this helps, but please let me know if you have additional questions.
  2. I am thinking about buying this ab (RPE65 Antibody); you have a nice picture showing how it is working in a saggital retinal section. Could I have the protocol that was used in this labeling? Frozen sections? Antigen retrieval?
    • Thank you for your email! We do not have a specific protocol for this Ab. Please see the Immunohistochemistry-Frozen Protocol our lab follows. The recommended dilution for IHC-Fr is 1:250 and antigen retrieval is not neccessary as the the protein is located in the cytoplasm.
  3. We have a question regarding species-specificity for this antibody. Does it work on rat? We'd like to use it on rat eye cryosections. But on the data sheet, only Bovine, Human, Mouse and Porcine were listed.
    • We have not tested RPE65 on rat samples. There is 93% similarity between the rat and bovine proteins, which is very promising but I still cannot guarantee that it will work. If you would like to test this antibody in rat samples, you would qualify for the Innovator's Reward Program which rewards our customers for trying our antibodies in previously untested species and applications.
  4. For clarification, is the 1:250 the recommended dilution for only IHC-F or all applications preceding IHC-F on the data sheet? If not, is there a recommended dilution for IHC-P? Do you have any information on antigen retrieval? Citrate buffer or higher pH (EDTA)? Temperature? Time? Regarding incubation time, is 1 hour at room temperature or overnight at 4C recommended?
    • The dilution of 1:250 should suffice for IHC-P as well as frozen sections. Unfortunately this item was tested by an outside collaborator who did not provide us with the protocol they used. Generally we recommend using antigen retrieval with citrate buffer and incubating for 1 hour at RT. Some antigens may be tricky and require overnight incubation. As all samples are different, this usually has to be user determined.
  5. Do you recommend an antigen retrieval step for this antibody : RPE65 Antibody (401.8B11.3D9)?. My application is IHC-paraffin cross section!
    • Yes, we do recommend antigen retrieval step for NB100-355 and in our IHC validation for this product, heat induced method was employed. You may use citrate buffer (10mM Citric Acid, 0.05% Tween 20, pH 6.0) for this purpose. Please view more information on antigen retrieval protocols.
