General description

Thyroxine or T4 is a thyroid hormone responsible for regulation of the body′s basal metabolic rate and essential for growth, development and heart and nervous system function.

This Certified Spiking Solution^® is suitable for use in LC-MS/MS testing methods as starting materials in preparation of linearity standards, calibrators, and controls.

Biochem/physiol Actions

L-Thyroxine (T₄) and triiodo-L-thyronine (T₃) are iodine-containing hormones produced from thyroglobulin in the thyroid follicular cells. The stimulation of metabolic rate and regulation of growth and development by these hormones appear to be due to their effects on DNA transcription and, thus, protein synthesis.
