Western blot analysis was performed on whole cell extracts (20 ug lysate) of Hep G2 (Lane 1), PC-3 (Lane 2), MCF7 (Lane 3), Mouse Heart (lane 4), HEK-293 (lane 5), HeLa (lane 6) and Mouse Kidney (lane 9). The blots were probed with Anti-Somatostatin Receptor 5 Rabbit Polyclonal Antibody (Product# PA3112, 1:4000-1:6000 dilution) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.4 ug/ml, 1:2500 dilution). Two bands ~ 42 and 39 kDa corresponding to Somatostatin Receptor 5 was observed across cell lines and tissues tested except for HEK-293. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 4-12 % Bis-Tris gel (Product # NP0322BOX), XCell SureLock™ Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane with iBlot® 2 Dry Blotting System (Product # IB21001). The membrane was probed with the relevant primary and secondary Antibody using iBind™ Flex Western Starter Kit (Product# SLF2000S). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

PA3-112 detects the Somatostatin Receptor 5 in human samples.
PA3-112 has been used successfully in Western blot, immunocytochemistry, and immunohistochemistry procedures. In Western blot analysis of SSTR5 transfected HEK-293 cells this antibody detects a ~54-63 kDa protein representing SSTR5.
The PA3-112 immunogen is a synthetic peptide corresponding to residues Q(344) E A T P P A H R A A A N G L M Q T S K L(364) of human SSTR5.
Somatostatin Receptor Type 5 (SSTR5) has been reported to be expressed in adrenal, aorta, brain, breast, eye, heart, pancreas, prostate, skeletal muscle, small intestine, and thyroid. ESTs have been isolated from cartilage libraries.
G-protein Coupled Receptors (GPCRs) comprise one of the largest families of signaling molecules with more than a thousand members currently predicted to exist. All GPCRs share a structural motif consisting of seven membrane-spanning helices, and exist in both active and inactive forms. An array of activating ligands participate in the conformation of GPCRs which leads to signaling via G-proteins and downstream effectors. Ongoing studies have also shown the vast series of reactions which participate in the negative regulation of GPCRs. This "turn-off" activity has tremendous implications for the physiological action of the cell, and continues to drive pharmacological research for new drug candidates. Two blockbuster drugs which have been developed as GPCR-targeted pharmaceuticals are Zyprexa (Eli Lilly) and Claritin (Schering-Plough) which have multi-billion dollar shares of the mental health and allergy markets, respectively
