A flow cytometric assay was used to detect the lytic and binding capacities of both fresh peripheral blood lymphocytes and purified Leu-19+ natural killer cells against head and neck cancer cell lines. Results demonstrated that natural killer cell-mediated cytotoxicity and effector-target conjugate formation evaluated by flow cytometry was significantly correlated with the standard chromium 51 release assay and the single-cell microscopic assay, respectively. The sorted Leu-19+ natural killer cells demonstrated higher lytic capacity with a corresponding higher binding rate compared with the unsorted peripheral blood lymphocytes and sorted Leu-19 cells. Flow cytometric analysis of natural killer cell activity (a rapid, simple, and quantifiable procedure) is an alternative to the standard chromium 51 release assay.
