【求助/交流】利用 vitaminC测量利福霉素含量的原理
|
|
For assay,the fermentation was collected after 7–8 days of cultivation at 28 °C. The filtered culture fluid was diluted with 0.2 M phosphate buffer (pH 4.5), and 0.5 ml was subsequently mixed with 4.5 ml 0.2 M phosphate buffer (pH 4.5) containing 0.1% vitamin C and 4.5 ml 0.2 M phosphate buffer (pH 4.5) containing 0.1% nitrite. 在网上看到一个关于利用 vitaminC测量利福霉素含量的方法，请问有没有人知道这种测量方法的原理？ |
