SepSphereTM Alprenolol Agarose

  • Structure of alprenolol agarose
  • Alprenolol agarose package
Calculated at checkout

Alprenolol is an antagonist for ß1 and ß2 adrenergic receptors. Alprenolol agarose affinity chromatography was first introduced by Lefkowitz R. J. in 1979 for the purification of erythrocyte ß-adrenergic receptor based on ligand-receptor interactions. It is now routinely used for the purification of functionally active ß1 and ß2-adrenergic receptor.
