With the development of laboratory cell culture, in addition to primary culture, the preservation of artificially developed cell lines is becoming increasingly important. The advantages of cryopreservation of cell lines are as follows: 1. reducing gene drift; 2. Slow down the aging of cell lines; 3. Stable phenotype; 4. Reduce opportunities for microbial pollution and cross contamination. The principle of cell freezing is to minimize the formation of crystals within the cell, reduce the low-temperature damage caused by the high concentration of solute formed by water coagulation in the cell, and thus improve the survival rate of the cell during resuscitation. The number of cells frozen should ensure that the cryoprotectant is diluted at a ratio of 1:10 to 1:20 during resuscitation, and the concentration of the diluted cell is still higher than that of the normal passage of cells. This is because when the cryoprotectant is diluted 10-20 times, This concentration generally does not cause toxic damage to cells.

DMSO (cell cryopreservation) is one of the components of a classic cell cryopreservation solution, used for the cryopreservation of various mammalian primary cells, passage cell lines, hybridoma cells, etc. The solution is sterilized.
