方法 | For measurement of proliferation, cells were seeded in triplicate at 2×103 cells/well in 96-well culture plates and incubated overnight to allow cell attachment. The cells were incubated with the TGX221-loaded PHA nanoparticles, empty PHA nanoparticles, or free TGX221 for 24, 48, and 72 h. At designated time intervals, cells were quantified by a crystal violet staining-based colorimetric assay (Kueng et al. 1989). Briefly, cells were fixed by addition of 100 μl of 2.5% glutaraldehyde solution andincubated at room temperature for 30 min. Plates were washed three times by submersion in PBS solution. Plates were air-dried and stained by addition of 100 μl of 0.1% solution of crystal violet dissolved in deionized water and incubated for 20 min at room temperature, excess dye was removed by extensive washing with deionized water, and plates were air-dried prior to bound dye solubilization in 100 μ1 of 10% acetic acid. The optical density of dye extracts was measured directly in plates using a microplate reader (Bio-Rad Laboratories, Inc., UK) at 570 nm. |

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。
