Detection of Human TSH R by Western Blot.
Western blot shows lysates of human thyroid tissue. PVDF Membrane was probed with 2 µg/mL of Mouse Anti-Human TSH R Monoclonal Antibody (Catalog # MAB6534) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). Specific bands were detected for TSH R at approximately 55 and 83 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 7.
Human TSH R ELISA Standard Curve.
Recombinant human TSH R protein was serially diluted 2-fold and captured by Mouse Anti-Human TSH R Monoclonal Antibody (Catalog # MAB65341) coated on a Clear Polystyrene Microplate (Catalog # DY990). Mouse Anti-Human TSH R Monoclonal Antibody (Catalog # MAB6534) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).

Background: TSH R
Thyroid stimulating hormone receptor (TSH R; also thyrotropin receptor) is an 85 kDa (unglycosylated) member of the G-protein coupled receptor 1 family. Human TSH R is synthesized as a 764 amino acid (aa) precursor that contains a 20 aa signal sequence, a 393 aa extracellular domain (ECD), a 269 aa membrane spanning domain consisting of seven transmembrane segments, and an 82 aa cytoplasmic domain. The ECD contains six leucine-rich repeats (LRR) and six potential sites of N-linked glycosylation. There are two isoforms, long and short, produced by a splicing variant corresponding to aa 253-764 in the long isoform that is missing in the short isoform. Human TSH R is 86-87% aa identical to mouse and rat TSH R. TSH R is the receptor for thyroid stimulating hormone, which plays a central role in controlling thyroid cell metabolism.
