Crude plasma membranes were prepared from chick lens epithelial and fiber cells and assayed for specific binding of the beta-adrenergic antagonist dihydroalprenolol. Both membranes specifically bound the ligand, with the epithelial membranes exhibiting a greater number of higher affinity sites. This is the first demonstration of lens beta-adrenergic receptors using this type of assay and the first direct demonstration of beta-adrenergic receptors in lens fiber cells.
