IEDB IEDB Labeling two populations of cells with different levels of CFSE, pusling one population with an influenza peptide, injecting the cells into a mouse, and recoving cells 24 hours later. By comparing the recovery rate of cells with different CFSE labeling, it is possible to determine if there was specific killing of peptide pulsed target cells. in vivo cell killing assay organism metadata complete
