体外研究 |
Resazurin sodium (Diazoresorcinol sodium) is commonly used to measure bacterial and eukaryotic cell viability through its reduction to the fluorescent product resorufin.No viable bacteria are detected 24h post-inoculation following inclusion of Resazurin sodium in TSBc cultures of F.tularensis LVS at the concentration of 44μM.Lowering the Resazurin sodium concentration to as little as 4.4μM still results in a 10-fold reduction in viable F.tularensis LVS compare to growth medium alone.Both Resazurin sodium treatments result in a significant decrease in viable F.tularensis LVS bacteria over 22h.Treatment with Resazurin sodium significantly reduces the number of viable F.tularensis LVS bacteria in HEK293 cells 22h post-infection. |
推荐实验方法(仅供参考)
细胞实验: |
|
F.tularensis is cultured in TSBc supplemented with 44μM Resazurin sodium salt at 37℃ with shaking for 24h.At select time points,a Spectronic 200 Spectrophotometer is used to measure the absorbance at 600nm and 570nm to detect the presence of Resazurin sodium salt and resorufin,respectively.The ratio of these two optical densities is used to evaluate reduction of Resazurin sodium salt to resorufin over time. |
本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系,公式为:
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
摩尔浓度计算公式
用本工具协助配置特定浓度的溶液,使用的计算公式为:
开始浓度 x 开始体积 = 最终浓度 x 最终体积
