Scatchard's analysis of [3H]-moxestrol and [ 3H]-estradiol binding proves the existence of a single class of receptor sites having a dissociation constant of 0.18-2.4 X 10(-9) M.
Abstract
The binding of estrogen in preparations of human peripheral blood mononuclear cells, as well as by splenic and thymic cells is demonstrated by three different approaches (Dextran-coated charcoal method, whole cell assay, and gel filtration on a sepharose 4B column). Scatchard's analysis of [3H]-moxestrol (R2858) and [3H]-estradiol binding proves the existence of a single class of receptor sites having a dissociation constant of 0.18-2.4 X 10(-9) M. Physicochemical properties of the binder, including binding capacity and steroid specificity, are quite similar to those reported for the thymus of small mammalian species or human thymoma.
