Abstract

The invention discloses an inducing culture reagent for CIK (Cytokines Induced Killer) cells. The reagent is prepared from a reagent A: 50ng / ml anti-CD3 monoclonal antibody; a reagent B: 1000IU / ml IFN-gamma; a reagent C: 1000IU / ml IL-2 and 20ng / ml IL-15; a reagent D: 100IU / ml IL-1; a reagent E: 40ml of lymphocyte separation medium. The invention also discloses an inducing culture method for the CIK cells by using the reagent. The reagent and the method, provided by the invention have the advantages that simple, high-efficient and stable induced CIK cells can be realized; by adding IL-15 in a classic preparation solution, multiplication number of the CIK cells and secretion of gamma-IFN can be better improved, and the anti-tumor effect of the CIK cells is improved; the cell inducing quality during CIK cell culture is high and the stability of cell multiplication number is good.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a CIK cell induction culture reagent and a culture method thereof. Background technique [0002] As the fourth new method of treating cancer after surgery, radiotherapy and chemotherapy, immune cell therapy has made great progress in recent years. Currently, immune cells have been widely recognized by the medical community with their efficient tumor-killing activity and no side effects. CIK As a relatively mature treatment method in immunotherapy, there are currently many induction methods, and their quality and quantity are also uneven; there are also researches on the preparation of CIK in different directions, but in practical applications, due to many cytokines and preparations, Due to the long period and different preparation standards, the preparation process is cumbersome and unstable, the quality and quantity of cells cannot be effectively controlled, and even pol...
