TSHR Antibody (4C1) is a mouse monoclonal IgG2a antibody that detects thyroid-stimulating hormone receptor (TSHR) in human samples through applications such as immunoprecipitation (IP), immunofluorescence (IF), and flow cytometry (FCM). Anti-TSHR antibody (4C1) plays a crucial role in the study of thyroid function, as TSHR is a glycoprotein receptor located on the surface of thyroid cells, where TSHR mediates the effects of thyroid-stimulating hormone (TSH). The binding of TSH to TSHR initiates a cascade of intracellular signaling that regulates thyroid hormone synthesis and release, which is vital for maintaining metabolic homeostasis in the body. TSHR (4C1) monoclonal antibody enables research into various physiological processes, including growth, development, and metabolism, making TSHR a key target for understanding thyroid-related disorders. Dysregulation of TSHR signaling can lead to conditions such as Graves′ disease, where autoantibodies activate TSHR, resulting in hyperthyroidism. The structural integrity of TSHR, particularly the third cytoplasmic loop, is essential for TSHR function, as this region is involved in the regulation of inositol phosphate and cyclic AMP formation, further underscoring TSHR importance in endocrine signaling pathways.

Can TSHR (4C1): sc-32262 monoclonal antibody be used in IF or IHC with mouse tissue or cells? Will there be non-specific staining?

Asked by: Germaine
Thank you for your inquiry. The use of mouse monoclonal antibodies with mouse samples is very common and typically poses no problem. To eliminate any potential cross-reactivity of an anti-mouse secondary detection reagent, TSHR (4C1): sc-32262 is available in a variety of direct conjugations, such as HRP, PE, FITC and AlexaFluors.
