产品介绍

生物活性
产品描述
Fusidic acid (Fusidine) is an antibiotic isolated from the fermentation broth of Fusidium coccineum.
激酶实验
DHODase activity is measured by the DCIP colorimetric assay. This is a coupled assay in which oxidation of DHO and subsequent reduction of ubiquinone are stoichiometrically equivalent to the reduction of DCIP. Reduction of DCIP is accompanied by a loss of absorbance at 610 nm (ε=21500 M/cm). The assay is performed in a 96-well microtiter plate at ambient temperature (ca. 25°C). Stock solutions of 10 mM leflunomide and A771726 are prepared in dimethyl sulfoxide (DMSO) and these are diluted with reaction buffer (100 mM Tris and 0.1 % Triton X-100, pH 8.0) to prepare working stocks of the inhibitors at varying concentrations. For each reaction, the well contained 10 nM DHODase, 68 μM DCIP, 0.16 mg/mL gelatin, the stated concentration of ubiquinone, 10 μL of an inhibitor working stock to give the stated final concentration, and reaction buffer. After a 5-min equilibration period, the reaction is initiated by addition of DHO to the stated final concentrations. The total volume of reaction mixture for each assay is 150 μL, and the final DMSO concentration is ≤ 0.01% (v/v). The reaction progress is followed by recording the loss of absorbance at 610 nm over a 10-min period (during which the velocity remained linear). Velocities are reported as the change in absorbance at 610 nm per minute, and each reported value is the average of three replicates. In experiments where the DHO or ubiquinone concentration is varied, the other substrate is held constant at 200 μM. To determine the inhibitor potency of leflunomide and A771726, the effects of varying concentrations of the two compounds on the initial velocity of the DHODase reaction is measured over a concentration range of 0.01?1.0 μM. In these experiments the DHO and ubiquinone concentrations are held constant at 200 and 100 μM, respectively.

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
