Lys-(Des-Arg9)-Bradykinin is a naturally occurring peptide agonist of the bradykinin B1 receptor (Ki = 0.12 nM in HEK293 cells expressing the human receptor).1,2 It is selective for bradykinin B1 over B2 receptors (IC50 = >30,000 nM in CHO cells expressing the human receptor).3 Lys-(Des-Arg9)-Bradykinin increases both mRNA and protein levels of the B1 receptor in IMR-90 human lung fibroblasts in a concentration-dependent manner.4 It induces contraction of isolated rabbit aorta (pD2 = 8.6).5 Lys-(Des-Arg9)-Bradykinin decreases blood pressure in LPS-treated rabbits in a dose-dependent manner.2

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。
