the quantitative relationship between receptor binding and hormone secretion at the single-cell level was investigated in the present study by combining a reverse hemolytic plaque assay for measurement of luteinizing hormone ( lh ) secretion from individual pituitary cells with an autoradiographic assay of 125i-labeled gonadotropin-releasing hormone ( gnrh ) agonist binding to the same cells .
