Cell TrackingCell movement and location studies require specialized probes that are nontoxic to living cells and are available in a range of fluorescent colors to match instrument lasers and filters and to accommodate co-staining with antibodies or other cell analysis probes. Choose passively loaded dyes for short- and long-term tracking or fluorescent fusion proteins for cell tracking over 5 or more days.

Short-Term Cell Tracking

  • Rapid loading (typically 15 min to 1 hr)
  • Short-term tracking (typically 3–6 generations)
  • Moderate resistance to photobleaching
  • Moderate brightness
  • Signal distribution throughout the cell

The simplest processes for monitoring cell movement and location use tracking probes that pass through the membrane into the cell and become membrane-impermeant after loading. Ideal tracking dyes are passed to daughter cells for multiple generations but do not transfer to neighboring cells on contact. CellTracker™ dyes exhibit ideal properties—they are stable, nontoxic at working concentrations, well retained in cells, and brightly fluorescent at physiological pH. CellTracker™ dyes have a wide range of emission spectra for easy combination with antibody staining.

Rat basophilic leukemia (RBL) cells labeled in suspension with CellTracker™ Blue CMAC, CellTracker™ Green CMFDA or CellTracker™ Orange CMTMR prior to plating.

Long-Term Cell Tracking

  • Typically 1-hour cell loading
  • Long-term tracking (typically 6–10 generations)
  • High resistance to photobleaching
  • Intense brightness
  • Punctate distribution throughout the cell

Longer-term tracking of cell movement and location requires probes that are more resistant to photobleaching and are retained through more cycles of cell division. Qtracker® probes provide intense, stable signals for long-term (6–10 generations) tracking. The eight distinct probe colors are resistant to photobleaching and provide intense punctate fluorescence within the cell, with different emissions from a single excitation for easy combination with antibody staining. Qtracker® probes have a wide range of emission spectra for easy combination with antibody staining.

Multiplexing Qdot® probes, dyes, and fluorescent proteins. U2-OS cells were transduced with CellLight® Plasma Membrane-GFP (green), followed by labeling with Qtracker® 655 Cell Labeling Kit (magenta), and HCS NuclearMask™ Blue (blue).

Cell Tracking with Fluorescent Proteins

  • Simple transduction protocol
  • Overnight incubation
  • Long-term tracking for up to 2 weeks or more than 10 generations
  • Red or green fluorescent protein
  • Can be multiplexed with fluorescent dyes or proteins

Transiently transduced cells express fluorescent fusion proteins at different locations within the cell for at least 5 days or up to 2 weeks in slow-growing populations. Labeled cells are easy to track, but not all cells within a population will express the fluorescent protein. CellLight® fluorescent proteins can be expressed in a variety of cell types including numerous transformed cell lines, primary cells, stem cells and neurons.
