体外活性 |
Displaying growth inhibition of HeLa cells with an IC50 value of 1.4 μM, Latrunculin B also modulates electrophysiological characteristics and arrhythmogenesis in pulmonary vein cardiomyocytes[1]. In pulmonary vein (PV) preparations, Latrunculin B (100 nM) decreases spontaneous electrical activity by 16±4%. Moreover, it reduces the late Na+ current, L-type Ca2+ current, Na+/Ca2+ exchanger current, and stretch-activated BKCa current in PV cardiomyocytes. Latrunculin B alters the transient outward K+ current and ultra-rapid delayed rectifier K+ current, while increasing the delayed rectifier K+ current in isolated PV cardiomyocytes. Additionally, at a concentration of 100 nM, Latrunculin B decreases intracellular Ca2+ transient and sarcoplasmic reticulum Ca2+ content in PV cardiomyocytes, attenuating stretch-induced increased spontaneous electrical activity and trigger activity[2]. |

对于不同动物的给药剂量换算,您也可以参考 更多...
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。
