| 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.
