Thyroid Stimulating Hormone Human Recombinant produced in HEK 293 cells.

HEK 293 cells.

Sterile Filtered White lyophilized (freeze-dried) powder.

Lyophilized from a concentrated 50mM ammonium bicarbonate.

It is recommended to reconstitute the lyophilized recombinant TSH in sterile 10 mM Sodium Phosphate, 150 mM Sodium Chloride, 1 mg/ml BSA, 0.1% Sodium Azide (optional), pH 7.4.

Lyophilized Recombinant TSH although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Recombinant TSH should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.

Greater than 95.0% as determined by SDS-PAGE.

The protein is biologically active using Siemens Centaur CP is standardized against WHO 3rd IS 81/565.

Thyroid-stimulating hormone (TSH), also known as thyrotropin, is a glycoprotein hormone produced by the anterior pituitary gland. Its primary function is to regulate thyroid gland activity by stimulating the synthesis and secretion of thyroid hormones, thyroxine (T4) and triiodothyronine (T3). Recombinant human TSH (rhTSH) has emerged as a valuable tool in clinical practice, particularly in the management of thyroid disorders and in diagnostic procedures involving the thyroid gland. This paper aims to provide an overview of research on rhTSH, including its mechanism of action, activity, and therapeutic applications.

The mechanism of action of rhTSH involves binding to the TSH receptor (TSHR) on the surface of thyroid follicular cells. This interaction activates intracellular signalling pathways, including cyclic adenosine monophosphate (cAMP) production and protein kinase A (PKA) activation. These pathways stimulate various cellular processes within thyroid follicular cells, such as iodine uptake, thyroid hormone synthesis, and secretion.
