Scientific background

GPR91 (Succinate Receptor 1), a member of the GPCR superfamily, is specifically activated by extracellular succinate outside the tricarboxylic acid cycle, resulting in activation of paracrine and endocrine effectors. Activation of GPR91 is associated with several diseases, including hypertension and diabetes1,2.

GPR91 was shown to regulate normal retinal vascularization, proliferative ischemic retinopathy and cortical revascularization post-ischemia. Activation of GPR91 influences different tissues such as kidney, heart, retina, white adipose tissue, and liver.

Through the activation of GPR91, succinate affects motility, migration, and growth of dendritic cells. In addition, the receptor directly promotes chemotaxis and potentiates activation initiated by Toll-like receptor agonists in dendritic cells1-3.

In the heart GPR91 mediates succinate-induced cardiomyocyte death. It was demonstrated that upholding levels of serum succinate can cause cardiac hypertrophy through the activation of the GPR911,2.

Anti-GPR91 (SUCNR1) (extracellular) Antibody (#ASR-090) is a highly specific antibody directed against an extracellular epitope of the rat protein. The antibody can be used in western blot, immunohistochemistry, indirect flow cytometry, and live cell imaging applications. It has been designed to recognize GPR91 from human, mouse, and rat samples.

Anti-GPR91 (SUCNR1) (extracellular)-PE Antibody (#ASR-090-PE) is directly conjugated to the Phycoerythrin (PE) fluorophore. This conjugated antibody has been developed to be used in immunofluorescent applications such as direct flow cytometry and live cell imaging.
