BMS 433796

The binding assay is performed in duplicate in an assay volume of 250 μl consisting of 25 μL of buffer (50 mM HEPES and 0.1% CHAPSO, pH 7.0) or 10 μM BMS-433796 to define nonspecific binding, 25 μL of buffer containing [³H]IN973, and 200 μL of homogenate (200 μg of protein). Incubation is initiated by the addition of the membrane homogenates at 25°C for 1 h. Binding reactions are terminated by filtration through Whatman GF/B filters using a cell harvester. Unbound radioactivity is removed by rinsing the filters with ice-cold wash buffer (PBS; pH 7.0). Filters are counted using a 2500TR liquid scintillation counter. Saturation data are analyzed by the nonlinear regression analysis program LIGAND. Binding curves are best fit to a one-site model, yielding the equilibrium dissociation constant (K_d) and the maximal number of binding sites (B_max)^[2].
