Anti Human TSHR[thyroid stimulating hormone receptor] Monoclonal Antibody (Clone No. 3A6)

The thyroid stimulating hormone receptor (TSHR) ,also known as LGR3, is a member of the leucine-rich repeat-containing G protein-coupled receptor (LGR) family. TSHR is expressed mainly in thyroid follicular cells and is activated by TSH, which regulates the growth and function of thyroid follicular cells.
Graves’ disease is a common type of autoimmune thyroid disease, in that the generation of autoantibodies against the TSHR causes continuous stimulation of the thyroid gland hyperthyroidism. It has been demonstrated that TSHR are present on the surface of melanoma cells, through which TSH promotes melanoma growth. It has been also showed that TSH/TSHR regulates transcription of the TNFα gene, osteoclast formation and osteoporosis arise from TSHR deficiency. This antibody is specific to TSHR and will be useful for research on autoimmune thyroid disease, osteoporosis, tumor such as melanoma.
