Flow Cytometry Core Facility

Flow Cytometry Core Facility

As one of the University of Toledo's core laboratories, the Flow Cytometry Core Facility provides access to instrumentation, assistance, and guidance, and offer information on current cytometric methods and applications as well as on dyes, cytometric bead arrays, multi-color panel kits, and other reagents. We welcoming UT investigators from all campuses and industrial researchers, technicians, and students from the surrounding community.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        



The Flow Core provides high-speed cell analysis for


Cell Tracking and Proliferation DNA Cell Cycle/Tumour Ploidy

DNA Synthesis/Degradation

Chromatin Structure

Gene Expression

Cell Membrane Potential

Surface Charge

Membrane Fusion/Runover

Ion Flux

Redox State

Oxidative Metabolism

Cellular pH Change

Cell Viability/Apoptosis/Necrosis

Intracellular Protein Staining

Total Protein

Enzyme Activity


Sulfhydryl Groups/Glutathione

Intracellular Cytokine/Chemokine Expression



In addition the Flow Core also offers high-speed cell sorting. This can be used to isolate/separate cell types (or vesicular bodies), rare populations, as well as specific clones post-transfection for further cell culture or analysis/experimentation—if a population can be labeled, distinguished, and gated, it can be sorted.

Samples are prepared by individual investigators who then deliver them to the Core for flow cytometric analysis or sorting. The core will not prepare cells but can provide assistance, guidance, and/or generation of publication-quality graphics and experimental design.
