| Stock Location | Stock in USA |
| MOQ | 1g |
1.MECHANISM OF ACTION
The peptide itself functions primarily as a substrate and antigen rather than a direct receptor agonist. It is processed by prohormone convertases to yield mature TRH (pyroGlu-His-Pro-NH₂), which then binds to TRH receptors (TRHR1/2) on pituitary thyrotrophs and neurons, activating Gq/11 signaling to increase intracellular calcium and stimulate TSH and prolactin secretion. In immunological applications, the fragment engages B-cell receptors to elicit antibody responses against TRH-related epitopes, enabling detection and quantification of both precursor and mature forms.
2.PRODUCT INDICATIONS
Prepro TRH (178-199) is indicated for research use in TRH biosynthesis and processing studies, including characterization of prohormone convertase activity, investigation of TRH precursor trafficking, and development of immunoassays for TRH and its precursors. It is suitable for academic and pharmaceutical research focused on hypothalamic-pituitary-thyroid axis regulation, neuroendocrine disorders, and antibody generation for immunohistochemistry or radioimmunoassays.
3.CLINICAL EFFICACY OF PRODUCT
As a research-grade peptide substrate and antigen, Prepro TRH (178-199) has no established clinical efficacy or therapeutic application in humans. Its utility is confined to preclinical studies where it facilitates understanding of TRH biology, validation of diagnostic assays, and support for research into thyroid and neuroendocrine pathologies, without direct patient use or regulatory approval for clinical intervention.
