方法 | Cell Growth Assays. Steroid-depleted cells were seeded into 12-well plates at a density of ∼1 × 104 cells per well or into 96-well plates at a density of 4,000 cells per well, in dextran-coated charcoal medium. After 24 h, monolayers were treated with E2 plus inhibitors either alone or in combination. The 12-well plates were treated for 6 days with daily changes. Cell number was then determined using a Z1 Coulter counter (Beckman Coulter). The 96-well plates were treated with a single dose and left for 96 h at which time cell viability was measured using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay as described previously (15). The interaction between R115777 and 4-OH-tamoxifen was analyzed by the median effect plot method described by Chou and Talalay (16). Calculation of the combination index took into account a nonfixed drug ratio and was based on the assumption that the action of the two drugs was mutually nonexclusive for the strict detection of synergism. A combination index < 1 indicates synergism, combination index = 1 indicates additivity, and a combination index > 1 indicates antagonism. Experiments were repeated thrice. |

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。
