Cell Tracing, Tracking, and Morphology

Invitrogen™ Molecular Probes™ fluorescent products provide a unique toolbox for studies of cell proliferation, migration, chemotaxis, and invasion. Labeling strategies range from expressing fluorescent proteins to loading long-lasting probes or cell-permeant cytoplasmic labels to fixable membrane tracers.

These diverse reagent classes can be used for labeling mammalian cells to view changes in morphology and location.

Cell tracers are frequently used in dye dilution assays to monitor cell proliferation using flow cytometry. Other trackers and tracers in a wide variety of colors provide efficient and sensitive methods for monitoring specific cells within a population by flow cytometry or imaging, in culture or in whole animals.

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 solutions.

Distinguish and quantitate bacteria with the LIVE/DEAD BacLigh Bacterial Viability and Counting Kit for flow cytometry.

Microbial Tracking by Flow Cytometry

Bacterial counting and enumeration assay kits for flow cytometry contain a mixture of fluorescent nucleic acid stains for bacterial identification, as well as a calibrated suspension of beads for accurate sample volume measurements.

Accurate detection of the live and dead bacteria in a sample is an important aspect of many experimental procedures in biotechnology, and due to the inherent differences between prokaryotic and eukaryotic cells, specialized dyes must be used to differentiate live and dead cell populations in bacteria.
