MULTISCREEN™ MEMBRANE PREPARATION
HUMAN RECOMBINANT α2A RECEPTOR
1 vial (15.6 mg/ml)
Expression vector containing full-length human α2a cDNA (GenBank Accession Number: NM_000681) with FLAG tag sequence at N-terminus
Liquid nitrogen upon receiving
Background: Adrenergic α2a receptor belongs to the group of nine adrenoceptors that mediate the biological actions of adrenaline and noradrenaline. The α2a receptor is expressed in the brain, spleen, kidney, heart and gastrointestinal tract. It is centrally predominant and exerts a tonic sympathoinhibitory function, whereas peripherally it has a vasoconstrictive effect. The α2a receptor is also involved in sedation, digestive functions and analgesia.
Application: [35S]GTPγS Binding Assay
