Abstract

Cytotoxicity assays are important in vitro tools to measure the lysis of desired target cells via an effector immune cell of choice. Specific lysis of the target cells can be determined by labeling the target cells with a radioactive isotope or fluorescent molecule, co-incubating it with an effector cell, then measuring the release of the labeled molecule in the supernatant. Here, we describe and compare different cell cytotoxicity assays using a chromium-51 (51Cr) release and DELFIA EuTDA fluorescent assay using K562 as the target cells and peripheral blood mononuclear cell (PBMC) derived natural killer (NK) cells as the effector cells.
