8 to 8), with a chelating agent (say, EDTA) with an added cryoprotectant such as glycerol or DMSO, is probably the safest matrix in which to store a nucleic acid which will be frozen and thawed.
Toxicity of cryoprotectant is the hot spot of cryobiology studies; therefore, the main challenge is to find the optimal concentration of cryoprotectant solution.
At the University of California, Irvine, we thawed another aliquot of synovial fluid, which had been frozen without cryoprotectant, and inoculated samples into BSK II medium (8).

Fahy has pioneered the use of cryoprotectant (medical-grade antifreeze) solutions that result in vitrification (glass) rather than freezing (ice).
Akron's glycerol-, serum- and DMSO-free cryoprotectant, CryoNovo(TM) T82, was developed as a non-toxic alternative to traditional DMSO-based cryopreservation media.
But curcumin and piperine which were used as a bioenhancers are unstable on long term storage at refrigerated condition and hence freeze drying is the viable option for long term stability so niosomes along with bioenhancers were freeze dried using 5% sucrose as cryoprotectant.
Our results differ from the findings of Theilacker and Shen (1993b) in that their study indicated that a cryoprotectant and acid were needed before freezing to stabilize RNA in brain cells of larvae of Walleye Pollock.
Seafood: tripolyphosphate in shrimp for mechanical peeling, pyrophosphate in canned tuna and crab to stabilize color and crystals, surimi ("crab/sea sticks") triphosphate and pyrophosphate as cryoprotectant to protein
3 that the polyunsaturated fatty acids of the powder without cryoprotectant (PS) are the most affected by freeze-drying (example 1,6% C18: 2 before freeze-drying to 0,7% after freeze-drying; 2,7% C18: 3 before freeze- drying to 1,5% after freeze-drying).
Plant vitrification method is done by using plant vitrification solution such as PVS2 and PVS3 which act as a cryoprotectant to the plant cells before being stored at the temperature of liquid nitrogen (-196[degrees]C).
