Real-Time Cell Health Monitoring, Cell-by-Cell, in 2D and 3D in the Far-Red

A reliable estimation of cell viability is central to assays for tumor cytotoxicity, apoptosis, and in vitro toxicology. DRAQ7™ is a membrane-impermeant DNA probe that enters leaky cells during apoptosis or necrosis to label the non-viable population. This white paper demonstrates the validation of DRAQ7 for use in long-term and real-time cell health assays, in combination with live cell-permeant DNA dyes for live/dead cell counting.
