alpha2B-Adrenoceptor (extracellular) Antibody

Affinity purified rabbit polyclonal antibody

  • WB - alpha2B-Adrenoceptor (extracellular) Antibody AG1375-025
    Western blot analysis of rat kidney (lanes 1 and 5), lung (lanes 2 and 6), liver (lanes 3 and 7) lysates and rat skeletal muscle membranes (lanes 4 and 8): 1. Anti-α2B-Adrenoceptor (extracellular) antibody (#AG1375), (1:200). 2. Anti-α2B-Adrenoceptor (extracellular) antibody, preincubated with the control peptide antigen.
  • IHC - alpha2B-Adrenoceptor (extracellular) Antibody AG1375-025
    Expression of α2B-Adrenoceptor in rat lung Immunohistochemical staining of rat lung paraffin embedded sections using Anti-α2B-Adrenoceptor (extracellular) antibody (#AG1375), (1:100). α2B-Adrenoceptor is expressed in the respiratory epithelium of the bronchioli (arrows). Hematoxilin is used as the counterstain.

Adrenoceptors (also called Adrenergic receptors) are the receptors for the catecholamines adrenaline and noradrenaline (called epinephrine and norepinephrine in the United States). Adrenaline and noradrenaline play important roles in the control of blood pressure, myocardial contractile rate and force, airway reactivity, and a variety of metabolic and central nervous system functions. The Adrenoceptors are members of the G-protein coupled receptor (GPCR) superfamily of membrane proteins. They share a common structure of seven putative transmembrane domains, an extracellular amino terminus, and a cytoplasmic carboxyl terminus.The Adrenoceptors are divided into three types: α1, α2 and β-Adrenoceptors. Each type is further divided into at least three subtypes: α1A, α1B, α1D, α2A, α2B, α2C, β1, β2, β31,2. The Adrenoceptors are expressed in nearly all peripheral tissues and in the central nervous system1,2. The α2B-Adrenoceptor has a distinct pattern of expression within the brain, liver lung and kidney, and recent studies using the knock out mouse system have shown that disruption of this receptor indeed affects mouse viability3, blood pressure responses to α2-Adrenoceptors agonists3 and the hypertensive response to salt loading4. Like the α2A-Adrenoceptor subtype, the α2B-Adrenoceptor undergoes short term agonist promoted desensitization5. This desensitization is due to the phosphorylation of the receptor by G-protein coupled receptor kinases (GRKs)6 which ultimately promotes uncoupling of the receptor from the G-protein subunit7. Abgent is pleased to offer a highly specific antibody directed against an extracellular epitope of rat α2B-Adrenoceptor. The Anti-α2B-Adrenoceptor (extracellular) antibody (#AG1375) can be used for Western blot analysis. It has been designed to recognize α2B-Adrenoceptor from mouse, rat and human samples.
