TLQP-21 TFA

生物活性

TLQP-21, a VGF-derived peptide endowed of endocrine and extraendocrine properties, is a potent G-protein-coupled receptor complement-3a receptor 1 (C3aR1) agonist (EC50: mouse TLQP-21=10.3 μM; human TLQP-21=68.8 μM). TLQP-21 activates C3aR1 to induce an increase of intracellular Ca2+. TLQP-21 is used for the research in regulation of nociception and other relevant physiologic functions[1][2].

体外研究
(In Vitro)

TLQP-21 is a peptide of 21 amino acids. At a dose of 3 μM TLQP-21 induces up to ~69% of the corresponding contraction promoted by acetylcholine[1][2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
