Competition for (−)-[125I]iodopindolol-binding sites in rat liver by ICI-118,551 and ICI-89,406: effects of age. Binding of (−)-[125I]iodopindolol to liver particulates from individual young (6 mo old) vs. old (24 mo old) rats was assayed in the presence of increasing concentrations of unlabeled ICI-118,551 (A) or ICI-89,406 (B), as described previously (57). Results from single representative animals are shown; curve-fitting analysis of competition data from 4 young (3–6 mo old) and 5 old (24 mo old) rats is presented in Table 1.
