Thyroxine (T₄) labeled with ¹²⁵I. Thyroxine is a thyroid hormone that is responsible for regulation or metabolism. T₄ detection by radioimmunoassay is a common test of thyroid disease. This product is offered at three specific activities. Specific activity indicates how much radioactivity there is per molecule of thyroxine. Several of our ¹²⁵I-labeled ligands are offered at maximum specific activity (2200 Ci/mmol if one ¹²⁵I labeling site is available, 4400 Ci/mmol if two labeling sites are available).
