General
First, you need to know both the excitation and emission wavelengths of your chosen fluorophore. You can check both spectrums for many common fluorophores at the following spectrum viewers:
BD Spectrum Viewer
Life Technologies Spectrum Viewer
eBioscience Spectrum Viewer
BioLegend Spectrum Viewer
See the What lasers/detectors do you have? question below for more information on our instruments. If you have further questions, feel free to contact us at FlowCytometry@arizona.edu

Flow cytometric analysis. Examples of assays include, but are not limited to: immunophenotyping, cell cycle analysis, DNA ploidy analysis, apoptosis/autophagy/necrosis, cell proliferation (BrdU incorporation), intracellular antigen/protein measurement and cytokine detection (bead assay), membrane potential measurement, intracellular pH/calcium (Ca++ flux) analysis, and oxidative stress detection.
High-speed aseptic cell sorting. Cell sorting based on cell surface marker immunostaining and/or side population staining. Our sorter is capable of sorting rare events or side-population cells. Example applications include isolation of tissue stem cells and cancer stem-like cells, isolation of fluorescently labeled cells in a mixed population, and isolation of cells within specific stages of the cell cycle.
