Human Thyrotrophin Receptor Monoclonal Antibody - Clone 4C1

Research tool for

  • Western blotting
  • Immunoprecipitation
  • Flow cytometry
  • Immunohistochemistry (frozen section)


Inhibits binding of TSH to TSH receptor by 70-80%.


The human thyrotrophin receptor (TSHR) is found primarily in epithelial cells of thyroid follicles where it induces (by cAMP) the phospholipase C and protein kinase A signal transduction pathways.  TSHR is the major pathogenic autoantigen in human autoimmune thyroid Graves’ disease.


Product Type

Hybridoma for monoclonal antibody


Bacterially expressed extracellular domain (residues 1-415 of humanTSHR fused to GST)



Cross-reacts with human and theoretically with rat, pig, sheep, mouse, dog, cat


Detects residues 378 - 384 of human TSHR.

Recognises nativeprotein.
