The invention relates to the technical field of tumor
cell killing, in particular to a method for in-vivo detection of the tumor
cell killing effect of NK cells, and the method comprises the following steps: S1, taking killing of male C57BL / 6 mouse NK cells on
Hela cells and other types of human-derived
tumor cells under in-vivo conditions as a model, and taking the
Hela cells as a contrast; s2, grouping the selected mice, and correspondingly performing
intraperitoneal injection of
isotype IgG, an anti-NK1.1
antibody and an anti-mouse NKG2D
monoclonal antibody; s3, preparing a
cell mixed solution of to-be-detected
tumor cells and
Hela cells; s4, injecting the cell mixed liquid into the body of the mouse in a
caudal vein injection manner; s5, killing each group of mice, and taking lungs to prepare a single-cell suspension; s6, detecting the number of CFSE positive cells and the number of PKH26 positive cells in the
mouse lung single-cell suspension by adopting a flow cytometer; and S7, calculating the
survival rate of the
tumor cells to be detected. The method well solves the problem that the killing effect of the NK cells on the
human tumor cells is difficult to accurately and truly evaluate in the prior art.
