Streptococcus agalactiae DNA lab quality control

Subculture	Brain heart extract medium (English name: BHIA/BHIB): brain extract 5.0g, heart extract 12.5g, peptone 5.0g, tryptone 10.0g, sodium chloride 5.0g, glucose 2.0g, disodium hydrogen phosphate 2.5g, agar 20.0g (not included in liquid medium),pH 7.4±0.2. Sterilization at 121 ℃ for 15min.
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 ℃;48-72h; 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 a group B streptococcus inactivated suspension. 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.
Sharing mode	Public welfare sharing
