Storage Temperature Depends on the Tissue
Bones and Tendons
- Stored below -40°C for the maximum shelf life which is 5 years after donation
- For no longer than 3 months, they can be kept between -20° and -40°
- Tissues can be placed in a +4°C refrigerator for no more than 24 hours and cannot be refrozen
- Needs to be stored below -40°C because the high concentration glycerol that it is kept in liquefies higher than this temperature
- Can be stored in a +4°C refrigerator for no longer than 24 hours once it is thawed (cannot re-freeze)
- Cryopreserved and stored in a specified liquid nitrogen cooled unit at -196° C
Taking Proper Care of Tissue Storage
Once all of the quality validation information has been reviewed and approved, the tissues can be released and distributed for the intended use. Human tissue is a useful resource and should be used with careful attention toexpiration periods, keeping stock levels stored under proper conditions . If the tissue is expired, it cannot be used, and it must be immediately thrown away.
