Weiyel Reference Materials
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 | Take it out of the refrigerator, and after it is completely melted, the vortex oscillates and mixes well, and it can be used. Note: The essential control product is inactivated particles, which need to be used after nucleic acid extraction, Extraction or purification reagents should be provided by oneself, and repeated freezing and thawing should be avoided before extraction. The minimum sampling amount is 200 μl. |
Growth conditions | 37 ℃;18-24h; Aerobic; |
Storage conditions | -80 ℃ |
Safety level | 2 |
Application | The essential control product is developed by Henan Industrial Microbial Strain Engineering Technology Research Center. It is an inactivated suspension of B- hemolytic streptococcus. It is obtained by adding stabilizers and digital PCR fixed values and then packaging. It can be used for method establishment and work standard assignment., Method confirmation and evaluation, product quality control, etc. |
