Triiodothyronine Salt

Analog of thyroid hormone that selectively binds to and activates β1 thyroid hormone receptor (TRβ1), 500 mg
SKU: SM-0011-0500



Product Description

Triiodothyronine Salt (or Liothyronine sodium/3,3’,5-Triiodo-L-thyronine sodium) is an analog of thyroid hormone that selectively binds to and activates β1 thyroid hormone receptor (TRβ1). This binding, in turn, regulates functions such as growth, metabolic activity, and differentiation (Bhat, et al.). Triiodothyronine Salt has been shown to promote enhanced maturation of cardiomyocyte populations, to the extent that beating cardiomyocytes may be maintained for up to six months (Burridge, et al.), in addition to playing a role in the induction of pluripotent stem cells from human keratinocytes (Aasen & Belmonte).

Product Synonyms:
Liothyronine Sodium, 3,3’,5-Triiodo-L-thyronine sodium, T3 Sodium Salt, 3,3',5-Triiodothyronine, Liothyronine, T3 Thyroid Hormone, Triiodothyronine
