GPR91 (formerly known as P2U2) is a G protein-coupled, dicarboxylic acid succinate receptor with the highest level of expression in the kidney, predominantly in the proximal tubules and the lowest in the liver and the spleen. GPR91 functions as a citric acid cycle intermediate succinate receptor. Two signaling pathways result from GPR91 activation, the pertussis-toxin-sensitive Gi/Go pathway and the pertussis-toxin-insensitive Gq pathway. Four amino acid residues are necessary for GPR91 activation by succinate: Arg 99, His 103, Arg 252 and Arg 281. GPR91 plays an important role in the succinate-induced hypertensive effect and may be involved in renovascular hypertension, a disease linked to diabetes, renal failure and atherosclerosis.

FAQs for SUCNR1/GPR91 Antibody (NBP1-00861). (Showing 1 - 1 of 1 FAQs).

  1. I am looking for a reliable GPR91 antibody suitable for immunohistochemistry and FACS. I know the Saphieia group from Montreal who used your GPR91 antibody in the past. Sadly they told me that that particular antibody is no longer available. Please can you advise me whether the new antibody NBP1-00861 truly does work for IHC/IF.
    • Yes, a couple of our other GPR91 antibodies were discontinued last year and at the moment we have only one GPR91 antibody (#NBP1-00861) which is one of our best selling products without even a single complaint. In our lab, we have tested GPR91-Antibody NBP1-00861 for WB and ICC/IF applications in Human, Mouse & Rat species. We have not tested this antibody in IHC and FLOW applications yet. However, some of our customers have used this antibody for IHC application and you may see following publications for that: Vargas et al. J Am Soc Nephrol. 2009 May;20(5):1002-11; Robben et al. Kidney Int. 2009 Dec;76(12):1258-67. Moreover, Hu et al (Exp Eye Res. 2013 Apr;109:31-9) and Aguiar et al. (Cell Calcium. 2010 Jan;47(1):37-46) have cited the ICC-IF use of this product. Because this antibody worked well in ICC-IF application and it is compatible with IF based immunodetection methods, I strongly believe that this antibody should work in FLOW application also. If you would be interested in testing this novel application, please take a look at our Innovator's Reward program.
