Abstract: The kinetics and equilibrium of the interaction of [3H]spiperone with binding sites on human lymphocytes have been studied using radioligand analyses. The process of [3H]spiperone binding to these sites can be explained by the model of ligand interaction with two independent binding sites (high-affinity site, KD1=3 nM, and low-affinity site, KD22Q nM), thus confirming the heterogeneity of the sites on human lymphocytes.
