| Subculturing | When using the essential control product, it should be moved to room temperature (20~25 ℃) for 10 minutes, the concentration value is 10 9~10 10PFU/mL, and the reference concentration is 1.71 × 10 9PFU/mL |
| Safety level | 1 |
| Application | The Escherichia coli phage PhiX174 quantitative standard quality control products, and collected phages by culturing host bacteria of Escherichia coli and phage PhiX174. The phage titer and lysis efficiency were determined by double-layer agar counting method, which was mainly used for phage PhiX174 positive quality control. |
