Description

General description

3,3′,5′-Triiodo-L-thyronine (T₃) is an endocrine hormone produced by the thyroid gland and is regarded as an active thyroid hormone at cellular level. Thyroxine (T₄) serves as a precursor for T₃ and is generated in extrathyroidal tissues.

Application

3,3′,5-Triiodo-L-thyronine sodium salt has been used for inducing thyroid hormone manipulations in mice. It has also been used In cell culturing of hippocampal, retinal, proximal tubule and glomerular explant.

Biochem/physiol Actions

3,3′,5′-Triiodo-L-thyronine (T₃) increases the rates of protein synthesis, stimulates the breakdown of cholesterol and effects embryonic development. In cell culture, T₃ regulates cell differentiation and protein expression. The interaction of T₃ with nonhistone proteins in the chromatin initiates the thyroid hormone activity. Thyroid hormones regulate the differentiation and development of tissues and affect a number of metabolic processes. The level of circulating T₃ hormone is reduced in hypothyroidism.

Physical form

powder-20 °C; stock-frozen in working aliquots, avoid repeated freeze/thaw, solution stable 2-8 °C, 30 days

Reconstitution

To prepare 20 μg/ml stock solution: add 1ml 1N NaOH per mg 3,3′, 5-triiodo-L-thyronine; gently swirl to dissolve. To this, add 49 ml sterile medium per ml 1N NaOH added.
