Total binding of [3H]2-MeSADP to washed platelets prepared from patient and normal blood. Binding of [3H]2-MeSADP to washed platelets was measured as described in “Patient, materials, and methods.” Specific binding was assessed in the presence of 500 μM unlabeled 2-MeSADP. Nonspecific binding values were subtracted from values obtained from total binding and these corrected values are represented as specific counts per minute (cpm). Data values are mean ± SEM from quadruplicate determinations from 1 experiment representative of 2 performed.
