细胞系 | N2a and SKNSH cells |
方法 | Cell viability determination Cells were seeded in serum-containing media onto 96-well plates at densities of 3 × 103 cells per well for N2a and 5 × 103 cells per well for SKNSH. Following overnight incubation, cells were treated with varying concentrations of triptolide in serum-free media and re-incubated for varying time courses at 37 °C. Controls were treated with serum-free media.Cell viability was determined using an MTT assay. Reagent was prepared by dissolving thiazolyl blue tetrazolium bromide in phosphate-buffered saline at a concentration of 2 mg/mL and filtering. After cells were incubated in 96-well plates and subsequently exposed to triptolide at varying doses and time durations, 20 μL MTT reagent were added to each well. Cells were re-incubated at 37°C for 4 hours, after which all liquid was aspirated from each well and absorbances were measured at 550 and 650 nm. These experiments were performed in triplicate and repeated 4 times. |

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。
