Figure 3

Specific cytotoxicity exhibited by EpCAM-specific CAR-NK-92 cells against EpCAM-positive target cells. The cytotoxic activity of CAR-NK-92 and Ctrl-NK-92 cells against EpCAM-negative or EpCAM-positive cells was determined using a 4-hour lactate dehydrogenase (LDH) release assay in a dose-dependent manner. ; ; ; ns: not significant.
