CellTracker CM-DiI is a fluorescent dye well suited for monitoring cell movement or location. This dye is well retained, allowing for multigenerational tracking of cellular movements. And the red excitation/emission spectra are ideal for multiplexing with green fluorescent dyes and proteins.

• Easy to use—remove medium, add dye, incubate 30 minutes, and image cells
• Fluorescent signal retention of >72 hours (typically three to six generations)
• Red excitation/emission spectra (553/570 nm maxima) ideal for multiplexing
• Low cytotoxicity—does not affect viability or proliferation

CellTracker CM-DiI fluorescent dye has been designed to freely pass through cell membranes into cells, where it is transformed into cell membrane-impermeant reaction products. CellTracker CM-DiI dye is retained in living cells through several generations. The dye is transferred to daughter cells, but not adjacent cells in a population. CellTracker CM-DiI dye is designed to display fluorescence for at least 72 hours, and the dye exhibits ideal tracking properties: it is stable, nontoxic at working concentrations, well retained in cells, and brightly fluorescent at physiological pH. Additionally, the excitation and emission spectra of CellTracker CM-DiI dye are well separated from GFP (green fluorescent protein) spectra allowing for multiplexing.
