WebMay 31, 2024 · Cytotoxicity is the primary function of CD8 + T-cells, also called cytotoxic CD8 + T lymphocytes (or CTLs). Quantification of this capacity is of major importance in diagnostic and research tools. While phenotypic characterization of CTLs is frequent and easily performed, their function is indeed more difficult to assess.
WebThe CytoTox 96® Non-Radioactive Cytotoxicity Assay is a colorimetric alternative to 51 Cr release cytotoxicity assays. The assay measures lactate dehydrogenase (LDH), a stable cytosolic enzyme that is released upon cell lysis. Released LDH in culture supernatants is measured with a 30-minute coupled enzymatic assay, which results in … WebAug 9, 2024 · Additional protocol variations might include testing different E:T ratios and incubation times to adapt the assay to different activation conditions. The duration of the co-culture of effector and target cells to test NK cytotoxicity has historically ranged from 4-16 h, though longer periods tend to result in increased spontaneous release 9 , 16 .
WebFeb 19, 2014 · The chromium-release assay developed in 1968 is still the most commonly used method to measure cytotoxicity by T cells and by natural killer cells. Target cells are loaded in vitro with radioactive chromium and lysis is determined by measuring chromium in the supernatant released by dying cells. Since then, alternative methods have been …
