产品描述 | Bradykinin (acetate) is an active peptide that is generated by the kallikrein-kinin system. It is a inflammatory mediator and also recognized as a neuromediator and regulator of several vascular and renal functions. Enzymatically produced from kallidin in the blood, it is a powerful vasodilator that causes smooth muscle contraction, and may mediate inflammation. It has a role as a human blood serum metabolite and a vasodilator agent. It is a tautomer of a bradykinin(2+). |
体内活性 | Exogenous bradykinin markedly inhibited TF expression in mRNA and protein level induced by LPS in a dose-dependent manner.?Moreover, the NO synthase antagonist L-NAME and PI3K inhibitor LY294002 dramatically abolished the inhibitory effects of bradykinin on tissue factor expression.?PI3K/Akt signaling pathway activation induced by bradykinin administration reduced the activity of GSK-3β and MAPK, and reduced NF-x03BA;B level in the nucleus, thereby inhibiting TF expression.Intraperitoneal injection of C57/BL6 mice with bradykinin also inhibited the thrombus formation induced by ligation of inferior vena cava. |
动物实验 | To study the effect of bradykinin on TF expression, we used Lipopolysaccharides (LPS) to induce TF expression in human umbilical vein endothelial cells and monocytes.?Transcript levels were determined by RT-PCR, protein abundance by Western blotting.?In the in vivo study, bradykinin and equal saline were intraperitoneally injected into mice for three days ahead of inferior cava vein ligation that we took to induce thrombus formation, after which bradykinin and saline were injected for another two days.?Eventually, the mice were sacrificed and tissues were harvested for tests[1]. |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
