激酶实验 Surface Plasmon Resonance (SPR) studies: The binding experiments are carried out on a ProteOn XPR36 biosensor at 25°C using the HTE sensor chip. The flow cells of the sensor chip are loaded with a nickel solution at 30 μL/min for 120 s to saturate the Tris–NTA surface with Ni(II) ions. Purified His-tagged STAT3 and STAT5 in PBST buffer (PBS with 0.005% (v/v) Tween-20 and 0.001% DMSO pH 7.4) is injected in the first and second channels of the chip respectively in the vertical direction at a flow rate of 25 μg/μL for 300 s, which attained, on average, ~8000 resonance unit (RU). After a wash with PBST buffer, inhibitors binding to the immobilized proteins is monitored by injecting a range of concentrations along with a blank at a flow rate of 100 μL/min for 200 s for each of these small molecules. When the injection of the small molecule inhibitor is completed, running buffer is allowed to flow over the immobilized substrates for the non-specifically bound inhibitors to dissociate for 600 s. Following dissociation of the inhibitors, the chip surface is regenerated with an injection of 1 M NaCl at a flow rate of 100 μL/ml for 18 s. Interspot channel reference is used for non-specific binding corrections and the blank channel used with each analyte injection served as a double reference to correct for possible baseline drift. Data are analyzed using ProteOn Manager Software version 3.1. The Langmuir 1:1 binding model was used to determine the KD values.
细胞实验 BTSC spheres are dissociated to single cells with the enzyme Accumax, seeded at 1500 cells/ 96-well and treated with drug or vehicle (DMSO) one day after plating. Cytotoxicity studies are repeated independently using BTSC lines 25M, 67EF, 73EF, 84EF and 127EF. BTSC spheres are dissociated to single cells as above and plated in 96 well plates in triplicate at 3000 cells/ 96-well. In both sets of experiments drugs are used as serial dilutions within the range of 5 μM to 100 nM in the first set and 25 μM to 10 nM. Cell viability following drug treatment is assessed three days later using the alamarBlue assay according to the manufacturer's instructions. All culture experiments are performed in triplicate with a minimum of three wells per condition.(Only for Reference)

TargetMol Calculator 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: 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。
