Immune cell preserving fluid

Abstract

The invention discloses immune cell preserving fluid. The immune cell preserving fluid comprises 0-50 U / mL of recombinant human interleukin-2, 0-10 mg / mL of human albumin, 0-1.5 mg / mL of alpha-1,4-glucan, 0.5-2.0 mg / mL of glucose, 3.5-5.0 mg / mL of sodium citrate, 2.0-3.5 mg / mL of sodium gluconate, 0.2-0.5 mg / mL of potassium chloride and 0.2-0.5 mg / mL of magnesium chloride. The immune cell preserving fluid has the advantages of being suitable for cell preservation within a wide temperature range, and capable of guaranteeing high cell viability of immune cells and facilitating follow-up cell experiment or clinical treatment.

Description

technical field [0001] The invention belongs to the technical field of cell culture, in particular to an immune cell preservation solution. Background technique [0002] Immune cell therapy is a new type of autoimmune anti-cancer treatment. It uses biotechnology and biological agents to culture and amplify immune cells collected from patients in vitro and then infuse them back into patients to stimulate and enhance immunity. Improve the immune function of the body, so as to achieve the purpose of treating tumors. Cell activity has a very important impact on the therapeutic effect, and how to maintain good cell activity during cell transportation is particularly important. The existing immune cell preservation solution has simple components and can only be used for short-term preservation or low-temperature preservation of cells. Under normal temperature conditions, the cell activity decreases rapidly, which seriously affects the therapeutic effect. Contents of the inventi...
