Incucyte Cytotox Red Reagent For Counting Dead Cells. Supplied As Five Vials (5 l Per Vial, 1 Mm In Dmso). Each Vial Sufficient For 100-200 Live Cell Imaging Cytotoxicity Tests In 96-Well Format. Incucyte Cytotox Reagents Are Highly Sensitive Cyanine Nucleic Acid Dyes Ideally Suited To A Simple Mix-And-Read, Real-Time Quantification Of Cell Death. Addition Of The Incucyte Cytotox Reagents To Normal Healthy Cells Is Non-Perturbing To Cell Growth Or Morphology And Yields Little Or No Intrinsic Fluorescent Signal. Once Cells Become Unhealthy Plasma Membrane Integrity Diminishes, Allowing Entry Of The Incucyte Cytotox Reagent And Yielding A 100-1000-Fold Increase In Fluorescence Upon Binding To Deoxyribonucleic Acid (Dna).
