Description
A 55453 is a radiated ionophore used as a high-affinity alpha 1-adrenergic receptor probe. It is a ligand that binds reversibly to rat hepatic plasma membranes with high affinity; thus it can be useful for the molecular characterization of alpha 1-adrenergic receptors in tissues.
Uses
A55453 is a prazosin analogue and a potent α1-adrenergic antagonist. 125I-A55453 is a high-affinity alpha 1-adrenergic receptor probe[1].
