20452-9Thyrotropin [Presence] in BloodActive

Part Description

LP14487-0   Thyrotropin
A glycoprotein hormone secreted by the adenohypophysis (anterior pituitary gland). Thyrotropin stimulates the thyroid gland by increasing the iodide transport, synthesis and release of thyroid hormones (thyroxine and triiodothyronine). Thyrotropin consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the pituitary glycoprotein hormones (TSH; Luteinizing hormone and FSH), but the beta subunit is unique and confers its biological specificity.
