Diagnostic Medicine/Pathobiology

Flow Cytometry Lab

The Flow Cytometry laboratory is housed in Mosier Hall, Room K208 of the College of Veterinary Medicine Complex. This multi-user core laboratory is equipped with state of the art flow cytometry analyzers by Sony (EC800) and Becton Dickinson (FACSCalibur), a multiplex MagPix instrument, and fluorescent activated cell sorting equipment by Beckman Coulter (MoFLO XDP).

Hours of Operation: M – F 8 – 5 pm, Call to schedule a time on the instruments

Sony EC800

The Sony EC800 is equipped with four lasers (405, 488, 561, and 640) with 6-color capabilities. This instrument can determine size, complexity, and electronic volume.  This flow cytometer can sample directly from a variety of plate or tube formats (ependorf tubes, falcon tubes, culture well plates, and tube rack) and is fully automated. The 405 laser allows the flexibility to use violet dyes. The 561 lasers provide the capability to excite a variety of fluorescent proteins (mCherry, mKate, link to fluorescent pdf chart).

FACSCalibur

The FACSCalibur is equipped with two lasers that emit light at 488 nm and 630 nm. There are three detectors (FL1, FL2, FL3) for the 488 laser and one detector (FL4) for the 630 laser.  This two laser cytometer allows the operator to analyze up to 4-color and 2 size parameters of cells or fluorescent-labeled particles. FACSCalibur is interfaced with a Macintosh computer and a publication quality color printer. Cell Quest and ModFit analysis software is available on two computers to analyze flow cytometry data including DNA and proliferation assays.

BioRad S3

The BioRad S3 is equipped with two lasers (488 and 561) with 4-color capabilities. The 561 lasers provide the capability to excite a variety of fluorescent proteins. This instrument can determine size, complexity, and sort cells.  The sorting operation is fully automated.  This instrument will be placed in the BRI in a level 2-biosafety hood (BioBubble).

MoFLO XDP

The MoFLO XDP is a "state of the art" analytical flow cytometer with high speed sorting capabilities. The MoFlo has five lasers (UV/violet/argon/green/red) with the capability to perform 10-color and 2 size parameter analyses and to routinely sort cells or particles at speeds up to 70,000 cells/second.

The research capabilities of this facility are very diverse and only limited by the imagination, available fluorochromes, and capabilities of the instruments. Examples of the research experiments that can be performed at this facility include but are not limited to: apoptosis studies, immunophenotyping, DNA content and viability of spermatozoa and other cell types, intracellular calcium levels, respiratory burst and phagocytic function, cell cycle, enzymatic activity, sorting of individual subpopulations of cells from a mixed population, sorting of GFP expressing cells from mixed cultures, and analysis of PCR products attached to microspheres.

MagPix

The MagPix by Millipore can analyze up to 50 analytes in a single sample. Examples are cytokine, chemokine, and serological panels. Call for consultation and quote for usage.
