SUMMARY

A new in vitro assay for thyroid-stimulating hormone (TSH) is described. The parameter of TSH action is the discharge of radioactive iodine from mouse thyroid glands labelled with 131I in vivo. The assay is sensitive to human TSH and gave consistent results during 1 yr. without seasonal variation. A potent preparation of long-acting thyroid stimulator gave a dose-response line parallel with human TSH. Fresh human serum was toxic to the assay preparation so that circulating TSH levels cannot be measured.
