equilibrium binding assays of high affinity sites for [ 3h ] -nitrendipine in ventricular homogenate preparations showed that the maximum number of [ 3h ] -nitrendipine binding sites ( bmax ) , which corresponds to the number of putative calcium channels , was not significantly different in normal and cardiomyopathic hearts : 79 ( sem 9 ) , 64 ( 14 ) and 69 ( 10 ) fmol.mg-1 protein in 4-6 hearts from f1b , bio 14.6 and chf 146 hamster strains , respectively .
