Cell tracers and cell trackers provide efficient and sensitive methods for monitoring specific cells within a population, by flow cytometry or imaging, in culture, or in whole animals. Strategies for labeling cells include expressing fluorescent proteins, cell-permeant cytoplasmic labels, and fixable membrane tracers.

Cell Tracking

Find live-cell probes for short-term tracking (3–6 generations), long-term tracking (6–10 generations), and fluorescent protein–based cell tracking.

Cell and neuronal tracing

Find fluorescent tracers for labeling of fresh or fixed tissue sections, in vivo imaging, and cultured cells via microinjection, iontophoresis, or pinocytosis.

Dextran conjugates

Dextran conjugates are offered at 3,000 MW to 2,000,000 MW and loaded by microinjection or iontophoresis for tissue sections, in vivo neurons, and cultured cells.

Cell Tracing by Flow Cytometry

Flow cytometry cell tracing probes are offered for short- and long-term cell tracing in fixable and non-fixable samples. These probes are available in multiple colors for a variety of laser lines and with a full range of supporting products for applications in cell counting, viability, and proliferation assays.
