产品描述 | Dupilumab (REGN-668) is a systemic immunomodulator for AD. Dupilumab is a fully human monoclonal antibody against the alpha subunit of the interleukin-4 receptor, which inhibits downstream signaling of IL-4 and IL-13 and has been shown to improve atopic dermatitis. |
体外活性 | Dupilumab inhibited mRNA expression of T cells, dc, eosinophils, inflammatory pathways and Th2-induced chemokine activation related genes in skin lesions, and showed no activity against IL-17A and significantly decreased IL-22 levels, but 300 mg Dupilumab significantly decreased the expression of IL-17-related genes. Such as elafin (PI3), IL23p19/IL23A and S100A8, and have inhibitory potential (CXCL1 and S100A7). Dupilumab (300 mg) inhibited hyperproliferation-related genes, such as K16, and decreased the expression of S100A, as measured by microarray and qRT-PCR.[1] |
体内活性 | In human whole blood, dupilumab inhibits IL-4 and il-13 to stimulate thymus secretion and activates chemokine/chemokine C motif ligand 17 (TARC/CCL17). (Clinical biomarker for atopic dermatitis) with yarnamore potency (50% inhibition at 0.24 to 0.52 nM and 0.26 to 0.27 nM).[1] |

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。
