The Flow Cytometry Core provides investigators with a resource for analytical and preparative studies of cells using flow cytometry. The Core offers FACS acquisition and analysis, cell sorting, and consultation for experimental design, interpretation and troubleshooting. Applications include immunophenotyping, intracellular staining, molecular and cellular probes such as Ca flux and GFP, CBA (Cytometric Bead Array), DNA cell cycle, TUNEL and Annexin V for apoptosis, sterile sorting for cloning and more. Both the LSRFortessa and Aria II have a green 561nm laser, which is optimal for detection of “mFruit” fluorescent proteins.
