Immunohistochemistry analysis of GPR31 was performed on human enteric ganglion tissue. To expose target proteins, antigen retrieval was performed by microwaving tissues for 20 minutes in 10mM sodium citrate buffer (pH 6.0). Tissue slides were probed with a GPR31 polyclonal antibody (Product # PA3-037) at a dilution of 1:3000, overnight at 4C in a humidified chamber. Tissues were washed, and detection was performed using an ABC kit composed of biotinylated goat anti-rabbit IgG, peroxidase-conjugated avidin, and 3-amino-9-ethylcarbazole (AEC) substrate in acetate buffer. Tissues were counterstained with hematoxylin and dehydrated to prep for mounting.

IHC (P) analysis shows positive staining of GPR31 in human enteric ganglion.
The G-protein-coupled receptor (GPCR) superfamily is comprised of an estimated 600-1,000 members and is the largest known class of molecular targets with proven therapeutic value. GPR31 is a high-affinity receptor for 12-(S)-hydroxy-5,8,10,14-eicosatetraenoic acid (12-S-HETE). 12-(S)-HETE is an arachidonic acid metabolite secreted by platelets and tumor cells, and known to induce endothelial cells retraction allowing invasive cell access to the subendothelial matrix, which is a critical step for extravasation or metastasis. Ligand-binding leads to activation of MAPK and NF-kappa-B pathways.
