Ability to measure cell viability and using the violet laser.No wash protocol just add and read for fast easily automated workflow.Multiplex with other Intellicyt kits like Cell Cycle for richer content.PrincipleThe Cell Membrane Integrity dyes are fluorescent molecules that are cell impermeant. Healthy cells with intact cell membranes will exclude the dyes. Unhealthy cells with compromised membranes will allow entry of the dye into the intracellular space. Upon entry to the cell the dye localizes to the nucleus and binds to DNA by intercalation.Multiplex with other Intellicyt kits like Cell Cycle for richer content.
