CELL PRESERVATIVE LIQUID

PROBLEM TO BE SOLVED: To provide a cell preservative liquid enabling cells to be preserved not only in a frozen state but also in a refrigerated state and improved in cell preservative performance, and to provide a method for easily preserving cells using the liquid. SOLUTION: The cell preservative liquid essentially contains saccharide(s), sodium ion and potassium ion, wherein the molar concentration of the sodium ion is equivalent to or higher than that of the potassium ion, thereby enabling cells to be preserved not only in a frozen state but also in a refrigerated state and thus providing the method for easily preserving cells. Furthermore, this cell preservative liquid enables cells to be cultured by inoculating the cells into a medium while suspending the cells in this liquid without undergoing steps such as washing the cells, therefore effecting a simple practice.
