NettetThe flow cytometry-based assay has been increasingly used to assess the cell-mediated cytotoxicity since the 1980s due to its advantages over the conventional radioactive 51 Cr release assay (CRA), such as higher sensitivity at the single-cell level and nonradioactivity. The basic principle of this assay is the usage of two dyes, one nontoxic dye for labeling …
