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 N-terminus, and a cytoplasmic C- 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. In general, the pharmacological properties of each subtype are quite homogenous across different species. However, this is not the case for the α2A subtype which was first isolated from human platelets3. This subtype shows different pharmacological properties from that of mouse and rat. For this reason, until molecular techniques significantly advanced, it was believed that human α2A and that of mouse and rat (termed α2D) were two different subtypes. Today, it is accepted that these two subtypes are in fact one gene product and is generally termed α2A. One of the main differences between this subtype from the different organisms is its affinity for yohimbine and rauwolscine; rat and mouse α2A displays less affinity compared to human3,4. Abgent is pleased to offer a highly specific antibody directed against an extracellular epitope of rat α2A-Adrenoceptor. The Anti-α2A-Adrenoceptor (extracellular) antibody (#AG1376) can be used for western blot analysis. It has been designed to recognize α2A-Adrenoceptor from mouse, rat and human samples.
