title: In situ molecular weight determination of rat brain [3H]phenytoin binding sites.
abstract: Using irradiation inactivation analysis of specific [3H]phenytoin binding to rat brain we have demonstrated that there are two different binding sites involved, with molecular weights of 73238 +/- 1535 (higher affinity site) and 108121 +/- 6935 (lower affinity site).
