Abstract

The invention discloses an NK cell culture kit and a usage method thereof and an NK cell obtained therefrom. The kit comprises an NK kit set and an NK consumable kit set, wherein the consumable kit set consists of a mononuclear lymphocyte cell separation centrifugal tube, a portable cell sample adding pre-filling stand, a cell culture bag tray and a cell culture bag; and the reagent box set consists of a pretreatment factor NK-A, a pretreatment factor NK-B, an amplification factor NK-C, an amplification factor NK-D, an amplification factor NK-E and a serum-free lymphocytes cell culture medium. More than 2*10<9> lymphocyte cells can be amplified within short time by matching the NK culture kit with basic experimental consumables, wherein the ratio of the NK cells (CD3-CD56+) can achieve more than 60%, thus providing convenience for amplifying NK cells in vitro on a large scale and conducting related studies and clinical trials.

Description

technical field [0001] The invention relates to the field of cell biotechnology, in particular to a set of NK cell culture kits capable of standardized production operations, a use method thereof and obtained NK cells. Using this kit and basic experimental consumables can conveniently expand a large number of NK cells in a short period of time, providing convenience for large-scale expansion of NK cells in vitro and related research and clinical trials. Background technique [0002] In 2000, the International Tumor Biotherapy and Gene Therapy Annual Conference pointed out that "immune cell therapy is the only possible way to completely eliminate cancer cells in modern technology". Dreams are turning into reality, and cancer is being gradually defeated by human beings. Cellular immunotherapy is the fourth largest cancer treatment mode after surgery, radiotherapy, and chemotherapy. As a hotspot in the clinical research of immunotherapy, NK cells have different induction and ...
