Incucyte® CytoLight Rapid Dyes for live-cell labelling enable simple, fast and highly efficient labelling of living cells. These dyes are well suited for identifying the location of cells within a population and monitoring the dynamic interactions between cells in mixed cultures. They are ideal for labelling cell types that are difficult to label using BacMam, lentivirus or other transfection-based labelling approaches (e.g. immune cells and primary cells). These dyes can be multiplexed with Incucyte® Annexin V, Caspase-3/7 or Cytotox reagents for simultaneous readouts of apoptosis or cytotoxicity.
