Background
Cell cryopreservation is a technique for placing cells in a low-temperature environment, reducing cell metabolism and facilitating long-term storage. Cell cryopreservation is one of the main methods for cell preservation. The cells are stored in liquid nitrogen at the temperature of-196 ℃ by using a freezing technology at a low temperature, so that the cells can be temporarily separated from a growth state and the cell characteristics can be stored, and the cells are recovered for experiments when needed. Moreover, a certain amount of cells are preserved appropriately, so that the cells can be prevented from being lost due to contamination or other accidents of the cultured cells, and the function of preserving the cells is achieved. In addition, some cells may be purchased, hosted, exchanged, and shipped in their cryopreserved form. When cells are frozen, a protective agent, namely glycerol or dimethyl sulfoxide (DMSO) with the final concentration of 5% to 15% is added into a culture medium, so that the freezing point of the solution can be lowered, and in addition, water in the cells can permeate out under the condition of slow freezing, the formation of ice crystals is reduced, and thus, the cells are prevented from being damaged. The method of 'slow freezing and fast melting' can better ensure the survival of cells. The standard freezing speed is from-1 to-2 ℃/min, the speed can be increased when the temperature is lower than-25 ℃, and the liquid nitrogen can be directly put into the liquid nitrogen after the temperature is lower than-80 ℃. When in use, the frozen cell stock solution needs to be subpackaged.
