Alprenolol is an antagonist for B1 and B2 adrenergic receptors.
This biotin-alprenolol conjugate is first designed and synthesized at CellMosaic® for our customers' usage of detecting B-AR.
Alprenolol is derivatized with a cysteamine linkage first at a position that is known to not interfere with the receptor binding, then reacts with biotin NHS ester to form the conjugate.
