Flow cytometry is used extensively throughout the life and biomedical sciences, and can be applied in any scenario where a researcher needs to rapidly profile a large population of loose cells in a liquid media.

When additional information is required, antibodies tagged with fluorescent dyes, and raised against highly specific cell surface antigens can be used to better identify and segregate specific sub-populations within a larger group.

Columbia Biosciences manufactures and sells antibodies, antibody conjugates, secondary antibody conjugates, streptavidin conjugates and fluorescent dyes (unconjugated) for use in flow cytometry/FACS.
