Abstract

The invention provides a cell preservation solution, comprising the following components: 30-120mM osmotic pressure stabilizer, 2-6mM carbohydrate, 0-10mM reducing agent, 0-120mM electrolyte solution, 25-60mM amino acid; the cell preservation The osmotic pressure of the liquid is 310-350mOsm / L. The cell preservation solution of the present invention can effectively reduce cell metabolism and reduce low temperature damage under low temperature conditions, facilitate the preservation of living cells during transportation, and facilitate the short-term preservation of functional active cells by institutions.

Description

technical field [0001] The invention belongs to the technical field of cell preservation, and in particular relates to a cell preservation solution and its application. Background technique [0002] Cells are the basic structural units of organisms, and the quality of cells will affect the state of the body. Cells are widely used in scientific research and clinical practice. The key to its application is the acquisition of a large number of donor cells and the overcoming of immune rejection. The acquisition of a large number of donor cells is mainly solved by in vitro cell culture and preservation. [0003] At present, there are still some problems in cell preservation, such as inconvenient transportation, inconvenient temporary storage, rapid decline in cell activity during transportation, and easy accumulation of cells into clumps. After the cells are transported for a long time, the viability of the cells is very low, and a large number of cells die, which directly affec...
