| Subculture | Columbia blood plate (English name: CA-B): casein pancreatin digest 10.0g, cardiopancreatin digest 3.0g, corn starch 1.0g, meat gastric enzyme digest 5.0g, yeast extract 5.0g, sodium chloride 5.0, agar 20.0g, distilled water 1.0L,pH 7.3±0.2. After sterilization at 121 ℃ for 15min, cool to 55 ℃, add 5% sterile defibrated sheep blood, shake well, pour the plate and cool it for later use. |
| Subculturing | This standard should be taken out from the low temperature environment before use and balanced to room temperature. Please centrifuge before opening the lid (12000rmp,60s); After opening the lid, add 100 μL of enzyme-free and sterile water to dissolve, shake evenly, and use after instantaneous centrifugation. |
| Growth conditions | 37 °;3-4 days; 5% CO2; |
| Storage conditions | -80 ℃ |
| Safety level | 1 |
| Application | Helicobacter pylori DNA standard is mainly used for positive control, nucleic acid detection kit development, and related research. |
| Sharing mode | Public welfare sharing |
