细胞系 | MV4-11 and RS4;11 cells |
方法 | Cellular assays. MV4-11 and RS4;11 cells were cultured in Iscove media with 10% fetal bovine serum (FBS) and RPMI complete with 10% FBS, respectively. For proliferation assays, cells were cultured overnight in low serum media (0.5% FBS), then seeded in a 96-well plate at 40 000 cells per well. Inhibitors were added to the cells and incubated at 37°C for 72 hours. Cell viability was measured using the Cell Titer-Blue Cell Viability Assay from Promega. To measure inhibition of FLT3 autophosphorylation, cells were cultured in low serum media (0.5% FBS) overnight and seeded at a density of 400 000 cells per well in a 96-well plate the following day. The cells were incubated with inhibitors for 2 hours at 37°C. To induce FLT3 autophosphorylation in RS4;11 cells, 100 ng/mL FLT3 ligand (R&D Systems) was added for 15 minutes after the 2-hour compound incubation. Cell lysates were prepared and incubated in 96-well plates precoated with a total FLT3 capture antibody (R&D Systems). The coated plates were incubated with either a biotinylated antibody against FLT3 (R&D Systems) to detect total FLT3 or an antibody against phosphotyrosines (Millipore) to detect FLT3 autophosphorylation. In both cases, a SULFO-tagged streptavidin secondary antibody was used for electrochemiluminescence detection on the Meso Scale Discovery platform. |

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。
