Target Details for Thyroxine T4

Target: Thyroxine T4 (T4)

Alternative Name: Thyroxine

Target Type: Amino Acid

Background: Optional[Gene Symbols]: Thyroxine (T4), the primary hormone produced by the thyroid gland, plays a vital role in regulating metabolism, growth, and development. This hormone is synthesized from tyrosine residues in thyroglobulin and contains four iodine atoms, making it a key component of iodine metabolism in the body. T4 exerts its effects by being converted into the more active triiodothyronine (T3), which influences numerous cellular processes by binding to thyroid hormone receptors.

Research has highlighted the critical involvement of thyroxine in the pathogenesis of various diseases, including hypothyroidism, hyperthyroidism, cardiovascular disorders, and metabolic syndromes. Dysregulation of T4 levels affects energy homeostasis, thermogenesis, and tissue differentiation, with far-reaching impacts on nearly every organ system. Moreover, thyroid hormone imbalances have been linked to alterations in other endocrine pathways, emphasizing the interconnected nature of T4 in maintaining physiological and metabolic equilibrium.

The T4 ELISA Kit is a competitive enzyme immunoassay developed for rapid detection and quantitation of T4 in serum, plasma, cell supernatant or urine samples collected from humans. The quantity of T4 is determined by a known T4 standard curve. This kit has a high sensitivity of approximately 0.494 ng/mL. Each kit provides sufficient reagents to perform up to 96 assays, including standard curve and unknown samples.
