title: Demonstration of triiodothyronine binding sites of Tetrahymena by a new scanning autoradiography method.
abstract: Binding of 125I-triiodothyronine to the surface of Tetrahymena was studied by scanning autoradiography. Specific binding sites were found which were confined to cilia and the mouth region. The experiments contribute new data to the phylogenesis of the membrane pattern.
