Big Endothelin-1 (1-38) (human) (trifluoroacetate salt)
(Synonyms: BET-1 (1-38) (human)) 目录号 : GC42930A peptide precursor of endothelin-1
Sample solution is provided at 25 µL, 10mM.
Big endothelin-1 (BET-1) (1-38) is a peptide precursor of endothelin-1 produced by vascular smooth muscle and endothelium. BET-1 is converted to endothelin-1 by endothelin-converting enzyme (ECE) and to endothelin-1 (1-31) by chymase. It is also converted to endothelin-1 (1-32) by matrix metalloproteinase-2 (MMP-2). BET-1 (50 pmol) induces vasoconstriction in isolated rat mesenteric arteries, an effect that is blocked by the MMP-2 antagonist TIMP-2. In vivo, BET-1 (0.1-10 nmol/kg, i.v.) dose-dependently increases blood pressure and bradycardia and leads to renal and hindquarter vasoconstriction in rats as well as abdominal constriction in mice (ED50 = 0.043 mg/kg), effects that are reversed or prevented by the ECE inhibitor phosphoramidon . It also induces mesenteric vasoconstriction in rats. Unlike endothelin-1, BET-1 (100 pmol/kg, i.v.) increases water and sodium excretion in rats independent of the endothelin A receptor.

工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
