Functional assays allowing phenotypic characterization of different cell death parameters at a single-cell level are important tools for preclinical anticancer drug screening. Currently, the selection of cytometric assays is limited by the availability of fluorescent probes with overlapping spectral characteristics. Following on our earlier reports on green and orange fluorescent SYTO probes, we provide herein further insights into applicability of novel red-excitable SYTO stains (SYTO 17, 59–64) for multiparameter analysis of cell fate. In particular, SYTO 62 appears to be a spectrally favorable candidate.
