LSR Fortessa X-20 Special Order Research Product Flow Cytometer

Lasers: 405nm, 488nm, 561nm, 640nm
Fluorescent Markers: FITC, GFP, Alexa 488, Alexa 546, Alexa 647, PerCP-Cy5.5, APC, Alexa 700, APC-Cy7, PE, PI, 7-AAD, PerCP, PETxRed, PE-Cy5, PE-Cy7, BV421, PacBlue, BV510, AmCyan, BV650, BV785, or any equivalent wavelength fluorophores.


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.

LSR Fortessa X-20 Special Order Research Product Flow Cytometer

The Fortessa X-20 is equipped with 4 non-linear lasers (405, 488, 561, 640 nm) and filter configurations allowing for detection of up to 12 colors plus Fwd and Ssc parameters. The cytometer utilizes FACSDiva v8.0 acquisition software and generates FCS files compatible with all commercial analysis programs. Routine CS&T calibration allows for standardization between experiments, increasing the reliability of data generated over time. This cytometer accepts samples in 5.0 mL falcon tube format with a recommended sample volume of approx. 300+ uL.


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.
