Abstract Herein we describe a flow cytometry-based assay utilizing K-562 cells stably expressing green fluorescent protein (ATCC CCL-243-GFP) to quantify the cytotoxic activity of primary human natural killer cells. The assay was performed using cryopreserved natural killer cells, with a hands- on time of under two hours. Specific lysis ranged from 2% to 57%, depending on the effector: target ratio and the donor (n=2). For many applications this cell line may provide a more reproducible and preferable alternative to methods requiring pre-loading of cells with fluorescent or radioactive materials.
Cell lines CVCL_JM00; K-562-GFP
