Tocilizumab 是抗人白细胞介素-6 受体 (IL-6R) 的中和抗体,能够阻碍 IL-6 与 IL-6R 的结合,进而抑制经典和反式信号。它可用于研究类风湿性关节炎,对重症 COVID-19 冠状病毒病方面的研究具有显著效果。
产品描述 | Tocilizumab (anti-IL-6R) is a humanized monoclonal antibody that binds to the interleukin-6 receptor |
细胞实验 | Objective: To validate that IL-6 signaling is essential for TAM (tumor-associated macrophages)-enhanced CSC (cancer stem cells) function. Concentrations: 5 μg/ml. Incubation Time: 72 h. Method: For co-culture experiments, 12-well Transwell chambers were used with 2×105 HepG2 or Hep3B cells seeded in the lower chamber one day before co-culture and either 5×105 or 1×106 TAMs added in the upper chamber. Tocilizumab or human IgG antibody were added in indicated experiments to selected wells. After 24 to 72 hours, HCC cells and CD14+ TAM cells were collected separately for analysis. Cells:HepG2 cell lines, TAMs isolated from HCCs (hepatocellular carcinoma) |

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。
