A bioluminescent enzyme immunoassay using estriol labeled with reversibly inactivated bacterial luciferase is described. An estriol derivative bearing an alkylthiolsulfonate is linked to the cysteinyl thiols of luciferase by formation of mixed disulfide linkages; thus, luciferase becomes inactive. After immunoassay, the inactive luciferase of the label bound to the immunoprecipitate is reactivated by incubation with dithiothreitol and the luciferase activity then is quantitated by a 20-s reaction performed with an automated luminometer (LKB 1251). Under the defined conditions, the labels are stable for at least 14 days as tested at 4 degrees C. A standard curve with a wide linear range from 50 to 6000 pg is demonstrated. This unique technology discussed here, therefore, offers exciting possibilities as a sensitive and rapid enzyme immunoassay for estriol.
