Extraction tubeNo DNA enzyme, no RNA enzyme, no endotoxin, no pyrogen. A drop volume of 30-50ul is sufficient for sample dispensing.
The storage conditions of the extraction tube mainly depend on its type and purpose. The following are the storage requirements for different scenarios:
Virus sampling tube:
Inactivated type: Can be stored at room temperature without special temperature control.
Non inactivated type: It needs to be stored at 4 ℃, avoiding high temperature or light exposure. It can be stored at 2-8 ℃ for short-term (<48 hours), and frozen at -20 ℃ or -70 ℃ for long-term use, and repeated freezing and thawing should be avoided.
Fecal collection and storage tube:
Type I tube: can store DNA for at least 2 years and RNA for up to 7 days at room temperature; If long-term storage is required, it should be placed in an environment of -20 ℃ or -80 ℃.
General requirements: All models must be stored in a dark environment at 2-37 ℃, away from corrosive substances; During transportation, foam boxes and biological ice bags shall be used to maintain low temperature and avoid violent vibration.
Blood sample storage tube:
Blood collection tube: It can be stably stored for 3 days at 18-25 ℃, and at least 50 months at -20 ℃ or -70 ℃.
PRP (Platelet Rich Plasma): can be stored in a shaking incubator at (22 ± 2) ℃ for 5 days or frozen at -80 ℃ for 6 months.
DNA/RNA storage tube:
Short term storage: It can be stored for several days to weeks at 4 ℃, and for 1-2 months at -20 ℃, but frequent freezing and thawing should be avoided.
Long term storage: -80 ℃ is a good choice and can be stored for several years. It is recommended to pack and freeze to reduce freeze-thaw effects.
