TSH (thyroid stimulating hormone), also known as thyrotropin, is a member of the cysteine knot growth factor superfamily. It is a heterodimer consisting of a 15 kDa unique TSH beta subunit and a 14 kDa alpha subunit, common glycoprotein hormone alpha that is shared with Luteinizing Hormone, Follicle Stimulating Hormone and Human Chorionic Gonadotropin. Production of TSH by the anterior pituitary gland is stimulated by the hypothalamic peptide TRH. TSH binds to thyroid TSH receptors to stimulate production of thyroxine (T4). In tissues, T4 is converted to the active form of thyroid hormone, triiodothyronine (T3), which stimulates the metabolism of almost every tissue in the body and completes a feedback loop by inhibiting TSH production. Serum TSH measurement is a crucial tool for the diagnosis of thyroid disorders. Increased serum TSH is an early and sensitive indicator of decreased thyroid reserve and overt primary hypothyroidism. Decreased TSH level is an indicator of TSH-independent hyperthyroidism (Graves' disease). For recombinant hTSH, conversion for IU is 1 µg of protein equals 7.9 x 10-3 IU.

AlphaLISA technology allows the detection of molecules of interest in a no-wash, highly sensitive, quantitative assay. In an AlphaLISA assay, a biotinylated anti-analyte antibody binds to the Streptavidin-coated Donor beads while another anti-analyte antibody is conjugated to AlphaLISA Acceptor beads. In the presence of the analyte, the beads come into close proximity. The excitation of the Donor beads causes the release of singlet oxygen molecules that triggers a cascade of energy transfer in the Acceptor beads, resulting in a sharp peak of light emission at 615 nm.
