| 方法 | In vitro efficacy of cidofovir against CHV-1 Madin–Darby Canine Kidney or Vero cells were plated into 96-well plates at 1*104 cells/well and maintained in Dulbecco’s minimal essential medium with 1 g/L glucose, l-glutamine, and sodium pyruvate (Cell Grow; Corning, Manassas, VA) containing 10% fetal bovine serum (Atlanta Biological, Flowery Branch, GA) and penicillin (200 U/mL)/ streptomycin (200 mg/mL) (Life Technologies, Grand Island, NY) for 24 h until confluent. Monolayers were infected with 5 PFU/well CHV-1 (a previously described field strain that was also utilized during the in vivo experimental study evaluating cidofovir) or HSV-1 strain F, respectively. After 2 h of incubation at 37 C, virus supernatants were removed, cells were rinsed once with phosphate-buffered saline (PBS), and 100 mL of sequential 2-fold serial dilutions of cidofovir (starting at 625 mM) was added to each well. Infection controls without cidofovir and noninfected drug-treated controls were also included. Plates were incubated at 37 C until a cytopathic effect (CPE) was visible in the infected nontreated controls, which was *72 hours postinfection (hpi) for CHV-1 and 48 hpi for HSV-1, respectively. Plates were rinsed 3 times with PBS, fixed in 80% ethanol for 10 min at -20 C, and stained with crystal violet (Fisher Scientific, Fair Lawn, NJ). Virusinduced CPE was scored as the percent of wells per dilution with observable plaque formation, and EC50 values were calculated using GraphPad Prism. |

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。
