WebThe live/dead assay is the most informative viability assay available which presents information regarding the number of viable and nonviable cells, cell morphology, and the distribution of cells. The live/dead assay is a dual color fluorescence assay which discriminates viable from dead cells based on intracellular esterase activity [ 31 ]. WebThey irreversibly conjugate to primary amine-containing proteins. Since there is a greater abundance of proteins inside the cell versus the cell surface, dead cells with a compromised membrane stain brighter than live cells with an intact membrane. Thus, they can be used to assess live vs. dead status of mammalian cells.
