产品介绍

生物活性
产品描述
Rose Bengal sodium is a potent inhibitor of VGlut and vesicular monoamine transporter (VMAT) (Ki of 19 and 64 nM for VGlut andVMAT, respectively)
体外活性
Rose Bengal固定在硅上,在暗环境中通过超声激活显示出良好的抗菌活性[1]。
细胞实验
Bacteria were grown to a concentration of 10^8 CFU/mL and then diluted with sterile saline by serial decimal dilutions to concentrations of 10^3–10^7 CFU/mL.?Three milliliters of bacterial suspensions was transferred into flat-bottom 2.5 cm diameter 20 mL vials.?Before the experiment, samples were taken from each vial to determine the initial bacterial concentration.?Free Rose Bengal at various concentrations or Rose Bengal immobilized onto silicone was added to all vials, except for the controls.?After adding Rose Bengal, all subsequent procedures were performed under dark conditions.?Vials with bacterial suspensions with or without Rose Bengal were held tight to the bottom of an ultrasonic bath in a plastic holder VU03H ?and treated by ultrasound at a frequency of 38 kHz and a field strength of 4.1 W/cm^3 for 1 to 10 min. After the treatment, 100 μL samples were diluted by several decimal dilutions and were spread over BHA plates with a Drigalsky spreader.?The plates were incubated at 37 °C overnight and the bacterial cell concentration was determined taking dilutions into account using the viable count method, where CFU were counted by means of a colony counter Scan 500.?In control experiments, bacterial cultures were tested in the absence of Rose Bengal without sonication, in the absence of Rose Bengal under sonication and in the presence of Rose Bengal without sonication[1].

体内实验配液计算器

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:
TargetMol | Animal experiments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 μLTargetMol | Animal experiments 一共给药动物 10 只 ,您使用的配方为 5% TargetMol | reagent 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 μLDMSOTargetMol | reagent ( 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:50μLDMSOTargetMol | reagent 母液,添加 300 μLPEG300TargetMol | reagent 混匀澄清,再加 50μLTween 80, 混匀澄清,再加 600μLddH2OTargetMol | reagent 混匀澄清

以上为“体内实验配液计算器”的使用方法举例,并不是具体某个化合物的推荐配制方式,请根据您的实验动物和给药方式选择适当的溶解方案。
