For live cell imaging to determine time required for killing and the average kills per NK cell, the cells were visualized every 70 s for 14 h and tracked manually. Web18 Feb 2024 · Killing assay. Briefly, carboxyfluorescein succinimidyl ester (CFSE)-labeled effector cells were incubated with targets at the indicated ratios for 6 to 24 hrs. ... CFSE-labeled effector cells were seeded at E:T of 5:1. Subsequently, the cells were observed and recorded by Nikon Ti-E Inverted Live Cell Imaging System Manuals (Japan) at 5% CO 2 ...
Web14 Aug 2024 · The FC-based NK cytotoxicity assay measures the killed target ratio, which can be considered a more convincing indicator of the killing ability of NK cells. Cytokine release [for example, the secretion of interferon gamma (IFN-γ)], the other type of NKA, differs from cytotoxicity. Web5 Jul 2014 · Make a fresh CFSElowstock solution by diluting 5 mM stock 1:10 in DMSO (a final concentration of 0.5 mM). Incubate the unpulsed target splenocytes with the higher concentration of CFSE (CFSEhigh): Add 1 µl of the 5 mM stock CFSE for each milliliter of unpulsed target cells (final concentration of 5 µM).
WebCFSE is non-fluorescent until it enters viable cells, where it is hydrolyzed by cytoplasmic esterase enzymes to release fluorescent amine-reactive dyes.
