WebOct 22, 2015 · Standard calcein release assay and image cytometry were performed within the same assay to determine NK cell killing of K562, 721.221 and Jurkat. The data is shown for each tumor cell line using NK cells expanded from 5 donors (n = 5). Cytotoxicity assay was performed in triplicate for each NK cell donor. WebCell killing occurs when critical targets within the cell are damaged by radiation. Therefore, radiation that deposits dose near critical structures is more likely to incur a biologic effect. ... First, the cytolytic activity of CIK cells makes themselves fuse with tumor cells and release perforin which inserts into the target cells and ...
