bindings of steroids were estimated by the dextran coated charcoal assay ( 0.001 % dextran and 0.1 % norite a ) and were evaluated by 5 approximately 20 % sucrose linear gradient centrifugation 1 ) effect of various metallic ions on steroid hormone-receptor binding ( determined by dextran coated charcoal assay . fig . 1 ) : thesteroid hormone-receptor interactions were markedly inhibited by cu++ , fe++ , and zn++ ions and moderately by mn++ , but k+ and ca++ increased of slightly affected the binding at concentrations between 10 ( -2 ) m and 10 ( -4 ) m .
