Western blot analysis was performed on whole cell extracts (30 ug lysate) of PC-3 (Lane 1), HEK-293 (Lane 2), T47D (Lane 3) and HEL 92.1.7 (lane 4). The blots were probed with Anti-alpha-2a Adrenergic Receptor Rabbit Polyclonal Antibody (Product# PA1048, 1:250-1:1000 dilution) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Secondary Antibody, HRP conjugate (Product # G21234,1:5000 dilution). Two bands 60 and 50 kDa corresponding to alpha-2a Adrenergic Receptor was observed across the cell lines tested. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 12 % Bis-Tris gel (Product # NP0342BOX), 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 following blocking with 5 % skimmed milk. Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

PA1-048 detects alpha-2A adrenergic receptor (A2AAR) from human, rat and mouse tissues.
PA1-048 has been successfully used in Western blot and immunohistochemistry procedures. By Western blot, this antibody detects an ~45 kDa protein representing A2AAR from mouse kidney membrane preparations.
The PA1-048 immunogen is a synthetic peptide corressponding to residues R(218) I Y Q I A K R R T R V P P S R R G(235) of the 3rd intracellular loop of human A2AAR. This sequence is completely conserved between human, mouse, rat, and porcine A2AAR.
Adrenergic receptors (ARs) are members of the 7-transmembrane domain G-protein-coupled receptor superfamily that bind the endogenous catecholamines epinephrine and norepinephrine. Pharmacological, structural, and molecular cloning data indicate significant heterogeneity within this receptor family. Nine receptor subtypes have been identified thus far including three alpha-1 AR subtypes (1A/D, 1B, and 1C), three alpha-2 ARs (2A, 2B, and 2C), and three beta AR subtypes (1, 2, and 3). ARs participate in either the onset or maintenance of several disease states including hypertension, cardiac dysfunction (congestive heart failure, ischemia, arrhythmias), diabetes, glaucoma, depression, and impotence.
A2AR subtypes inhibit adenylyl cyclase, suppress voltage-sensitive calcium channels, and activate receptor-dependent potassium channels. All of the A2AR subtypes inhibit adenylyl cyclase through coupling to members of the Gi/Go class of G proteins. They are an essential component of the neural circuitry regulating cardiovascular physiology. The physiological function of the A2ARs in the kidney is to regulate sodium/hydrogen exchange although the role of A2AR subtypes remains to be precisely determined.
