This method was successfully extended to human retinoic X receptor alpha , glucocorticoid receptor , and progesterone receptor , thus providing a basis for a new, faster assay to determine simultaneously the affinity and conformation of receptors when bound to a given ligand.
 ( protein: human retinoic X receptor alpha, None) , ( protein: glucocorticoid receptor, None) , ( protein: progesterone receptor, None)
