Immunohistochemistry analysis of GPR3 was performed on human pancreatic duct 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 GPR3 polyclonal antibody (Product # PA3-003) 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 GPR3 in human pancreatic duct tissue.
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. GPR3 is an orphan receptor with constitutive G signaling activity. GPR3 modulates a number of brain functions, including behavioral responses to stress, neurite outgrowth and amyloid-beta peptide generation suggesting that it may play a role in Alzheimer's disease.
