Ergosta-7,22-dien-3-one 是一种羊毛甾烷,能够从台湾灵芝的子实体中分离得到。Ergosta-7,22-dien-3-one 具有促炎特性,它能刺激一氧化氮的产生,诱导基因的表达,并诱导 J774A.1 细胞产生 TLRs、细胞因子、趋化因子和细胞粘附分子。
产品描述 | Ergosta-7,22-dien-3-one is a lanosterane that can be isolated from the substrates of Ganoderma taiwanensis.Ergosta-7,22-dien-3-one has pro-inflammatory properties, it stimulates nitric oxide production, induces gene expression, and induces the production of TLRs, cytokines, chemokines, and cellular adhesion molecules. |
体外活性 | Ergosta-7,22-dien-3-one, isolated from a wild Mexican strain of Ganoderma oerstedii. According study, Ergosta-7,22-dien-3-one did not present any cytotoxic effect on HeLa or J774A.1 cells, and it was able to stimulate nitric oxide production, induce the expression of genes, and induce the production of TLRs, cytokines, chemokines, and cellular adhesion molecules in J774A.1 cells, based on reverse-transcriptase polymerase chain reaction and enzyme-linked immunosorbent assay. Here we report a new pro-inflammatory property of Ergosta-7,22-dien-3-one, which should be considered as a possible adjuvant property in view of its biological activity.[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。
