                    | Subculture | Peptone: 10.0, beef powder: 3.0, sodium chloride: 5.0, agar: 15.0,pH: 7.3±0.1(25 ℃) | 
| Subculturing | Remove from the refrigerator, melt completely, vortex and mix well, ready to use. Note: The quality control is inactivated particles, which need to be used after nucleic acid extraction. The extraction or purification reagents should be prepared by themselves, and repeated freezing and thawing should be avoided before extraction. The minimum sampling volume is 200 μl. | 
| Growth conditions | 37 ℃;18~24 hours; | 
| Storage conditions | -80 ℃ | 
| Safety level | 0 | 
| Application | The quality control is developed by Henan engineering center of industrial microbial strain, which is E. coli inactivated bacteria suspension, which can be used for method establishment, work standard assignment, method confirmation and evaluation, product quality control, etc. through digital PCR value. | 
| Sharing mode | Public welfare sharing |
