Radioimmunoassay of canine growth hormone: enzymatic radioiodination.

abstract：:Testicular cytosol from Sprague-Dawley rats was shown to possess an estradiol binding component which exhibited the properties of a receptor. Specific binding of estradiol by the receptor was shown, at 4C in vitro, to reach equilibrium by 6 h. That level of binding was maintained at a plateau for 18 h. Estradiol bindi...
