1 an improved binding assay involving ( - ) - [ ( 3 ) h ] -dihydroalprenolol ( dha ) and kcl-washed cardiac membranes was developed to study beta-adrenoceptors in the canine heart quantitatively.2 receptor numbers varied from 3.8 to 7.1 pmol/g fresh tissue , showing a steady increase from left atrium -- > right atrium -- > right ventricle -- > interventricular septum -- > left ventricle .
