cryoprecipitation (s) (noun), cryoprecipitations (pl)
The process of forming a solid that settles from a solution: " The cryoprecipitation that forms when plasma is frozen and then thawed; which is especially rich in fibronectin (secreted proteins) and a blood clotting factor, that when acting together can form a blood clot shortly after platelets have broken at the site of the wound."
cryopreservation, cryopreserve
1. Maintenance of the viability of excised tissues or organs at extremely low temperatures.
2. The process of storing semen, ova, corneas, embryos, bone marrow, or body tissue at extremely low temperatures for future use.
