whereas low concentrations ( 10-200 mm ) of all these anions enhanced [ 3h ] strychnine binding , higher concentrations ( 0.2-3 m ) of thiocyanate , perchlorate , and iodide produced a robust inhibition of radioligand binding , and a more modest inhibition was observed with the same concentrations of nitrate and bromide .
