complement 3a

C3a 70-77 2TFA(63555-63-5(free base)) (Complement 3a (70-77)) 是对应于 C3a 的 COOH 末端的八肽。

C3a (70-77) TFA (Complement 3a (70-77) TFA) is a COOH-terminal fragment of the C3a anaphylatoxin peptide.

C3a (70-77) 是对应于 C3a 的 COOH 末端的八肽。

TLQP 21 acetate 是 G 蛋白偶联受体补体 3a 受体 1 (C3aR1) 的有效激动剂。 小鼠的 EC50 值为 10.3 μM，人的 EC50 值为 68.8 μM。它是一种 VGF 衍生肽，具有内分泌和内分泌特性。

TLQP-21 TFA, a VGF-derived peptide endowed of endocrine and extraendocrine properties, is a potent G-protein-coupled receptor complement-3a receptor1 (C3aR1) agonist (EC50: mouse TLQP-21=10.3 μM; human TLQP-21=68.8μM). TLQP-21 TFA activates C3aR1 to induce an increase of intracellular Ca2+. TLQP-21 TFA is used for the research in regulation of nociception and other relevant physiologic functions[1][2]. TLQP-21 TFA 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]. [1]. Elena Bresciani , et al.
