方法 | Cell Proliferation Assay. A modified tetrazolium salt assay was used to measure the inhibition of tumor cell growth. Cells were added to 96-well plates and propagated for 24 h before compound addition. The compound was serially diluted and added at a concentration range of 3 to 1,000 nmol/L to the plated cells. DMSO (0.03-0.003%) was included as a vehicle control. Cells were incubated in the presence of compound for 5 days. After incubation phenazine methosulfate (stock concentration 1 mg/mL) and 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt (stock concentration 2 mg/mL; Promega) were mixed at a ratio of 1:20 and added to each well of a 96-well plate. Reduction of 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt gave rise to a soluble formazan product that was secreted into the culture medium. After 4 h incubation, the formazan product was quantitated spectrophotometrically at a wavelength of 490 nm. Data were acquired using SOFTmaxPRO software, and 100% viability was defined as the A490 of DMSO-treated cells stained with 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt (the mean A490 of cells treated with DMSO at a range of 0.03-0.003%). Percent viability of each sample was calculated from the A490 values as follows: % viability = (A490 nm sample / A490 nm DMSO-treated cells × 100). The IC50 was defined as the concentration that gave rise to 50% inhibition of cell viability. |

建议您制定动物给药及实验方案时,尽量参考已发表的相关实验文献(溶剂种类及配比众多,简单地溶解目的化合物,并不能解决动物给药依从性、体内生物利用度、组织分布等相关问题,未必能保证目的化合物在动物体内充分发挥生物学效用)。
体内实验的工作液,建议您现用现配,当天使用;如在配制过程中出现沉淀、析出现象,可以通过超声和(或)加热的方式助溶。
切勿一次性将产品全部溶解。
请在下面的计算器中,输入您的动物实验相关数据并点击计算,即可得到该实验的总需药量和工作液终浓度。
例如您给药剂量是10 mg/kg,平均每只动物的体重为20 g,每只动物的给药体积是100 μL,动物数量为20只,则该动物实验的总需药量为4 mg,工作液终浓度为2 mg/mL。
1:鉴于实验过程的损耗,建议您至少多配1-2只动物的量;
2:为该产品最终给药时的浓度。
