Background: SUCNR1/GPR91

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.

Protocols

View specific protocols for SUCNR1/GPR91 Antibody - BSA Free (NBP1-00861):


Immunocytochemistry Protocol

Culture cells to appropriate density in 35 mm culture dishes or 6-well plates.

1. Remove culture medium and add 10% formalin to the dish. Fix at room temperature for 30 minutes.
2. Remove the formalin and add ice cold methanol. Incubate for 5-10 minutes.
3. Remove methanol and add washing solution (i.e. PBS). Be sure to not let the specimen dry out. Wash three times for 10 minutes.
4. To block nonspecific antibody binding incubate in 10% normal goat serum from 1 hour to overnight at room temperature.
5. Add primary antibody at appropriate dilution and incubate at room temperature from 2 hours to overnight at room temperature.
6. Remove primary antibody and replace with washing solution. Wash three times for 10 minutes.
7. Add secondary antibody at appropriate dilution. Incubate for 1 hour at room temperature.
8. Remove antibody and replace with wash solution, then wash for 10 minutes. Add Hoechst 33258 to wash solution at 1:25,0000 and incubate for 10 minutes. Wash a third time for 10 minutes.
9. Cells can be viewed directly after washing. The plates can also be stored in PBS containing Azide covered in Parafilm (TM). Cells can also be cover-slipped using Fluoromount, with appropriate sealing.

Immunohistochemistry-Paraffin Embedded Sections

Antigen Unmasking:
Bring slides to a boil in 10 mM sodium citrate buffer (pH 6.0) then maintain at a sub-boiling temperature for 10 minutes. Cool slides on bench-top for 30 minutes.

Staining:
1. Wash sections in deionized water three times for 5 minutes each.
2. Wash sections in wash buffer for 5 minutes.
3. Block each section with 100-400 ul blocking solution for 1 hour at room temperature.
4. Remove blocking solution and add 100-400 ul diluted primary antibody. Incubate overnight at 4 C.
5. Remove antibody solution and wash sections in wash buffer three times for 5 minutes each.
6. Add 100-400 ul biotinylated diluted secondary antibody. Incubate 30 minutes at room temperature.
7. Remove secondary antibody solution and wash sections three times with wash buffer for 5 minutes each.
8. Add 100-400 ul Streptavidin-HRP reagent to each section and incubate for 30 minutes at room temperature.
9. Wash sections three times in wash buffer for 5 minutes each.
10. Add 100-400 ul DAB substrate to each section and monitor staining closely.
11. As soon as the sections develop, immerse slides in deionized water.
12. Counterstain sections in hematoxylin.
13. Wash sections in deionized water two times for 5 minutes each.
14. Dehydrate sections.
15. Mount coverslips.



Western Blot Protocol

1. Perform SDS-PAGE with a 12% gel on samples to be analyzed, loading 25 ug of total protein per lane.
2. Transfer proteins to membrane according to the instructions provided by the manufacturer of the membrane and transfer apparatus.
3. Stain according to standard Ponceau S procedure (or similar product) to assess transfer success, and mark molecular weight standards where appropriate.
4. Rinse the blot.
5. Block the membrane using standard blocking buffer for at least 1 hour.
6. Wash the membrane in wash buffer three times for 10 minutes each.
7. Dilute anti-GPR91 primary antibody in blocking buffer and incubate 1 hour at room temperature.
8. Wash the membrane in wash buffer three times for 10 minutes each.
9. Apply the diluted HRP conjugated secondary antibody in blocking buffer (as per manufacturers instructions) and incubate 1 hour at room temperature.
10. Wash the blot in wash buffer three times for 10 minutes each (this step can be repeated as required to reduce background).
11. Apply the detection reagent of choice in accordance with the manufacturers instructions.
Note: Tween-20 can be added to the blocking or antibody dilution buffer at a final concentration of 0.05-0.2%.

FAQs for SUCNR1/GPR91 Antibody - BSA Free

Showing  1 - 1 of 1 FAQ Showing All
  • Q: 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.

    A:

    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.
