A flow cytometer uses laser light to detect particles in a fluid stream. Emissions scatter at different angles depending on particle size and internal complexity. The deflected light hits a series of detectors and the signals from these detectors are interpreted by computer software in real-time. This poster explores the use of flow cytometry in GFP-tagged Salmonella strains as positive controls for rapid qualitative Salmonella detection testing.
