Flow Cytometry Analyzers

Cytek Aurora: A spectral flow cytometer that has the 4 laser system (16V-14B-10YG-8R) which offers up to 40 fluorescent parameters. The Aurora has state-of-the-art optics that allow for excellent sensitivity and resolution without needing filter changes. The flat top beam profile lasers are 405 nm is 100mW (violet detector), 488nm is 50mW (blue detector), 561nm is 50mW (yellow-green detector), and the 640nm is 80mW (red detector). The FSC is based off the 488nm with two SSC, one VSSC off the 405nm and the other BSSC off the 488nm. Sampling rates are low 15uL/min, medium 30 uL/min, high 60uL/min and a plate high throughput at 100 uL/min. Does require a separate end analysis program (FlowJo, FCSexpress, ect.). This machine excels in high complexity panels for rare and dim populations. Please make sure on the weekends that QC has been run before doing your experiment.

Violet detector module 16 channels unevenly spaced bandwidth from 420-829 nm
Blue detector module 14 channels unevenly spaced bandwidth from 498-829 nm
Yellow-Green detector module 10 channels unevenly spaced bandwidth from 567-829 nm
Red detector module 8 channels unevenly spaced bandwidth from 652-829 nm

Two Beckman Coulter Gallios: The Gallios is a three laser benchtop analyzer equipped with a 22mW Argon 488nm laser, 25mW 638 laser, and a 40mW 405nm laser. All are solid state diodes which are spatially separated at 125um. Alignment is software controlled using Cyto System Mgmt software and can be controlled remotely. This allows for detection of five fluorescent parameters from the 488nm laser, three parameters from the 638nm laser, and two parameters from the 405nm laser in a proprietary "Boulevard" configuration for greater fluorescent resolution. With multiple measurements and angles of Forward Scatter and a gel coupled pickup filter lens assembly, the Gallios can resolve 0.4um diameter particles from background and maximize detection up to 40um. This instrument is equipped with a Multi-tube Carousel Loader system to automatically analyze multiple samples. Software for acquisition and analysis is the Beckman Coulter CXP, running on an Intel Pentium Core 2 Duo processor. Individual research personnel, following requisite training from the Flow Cytometry Core staff, may independently use and operate this instrument. It is available to trained users for full use even in off hours, including evenings, nights, and weekends. Access to the instrument during off hours is controlled by a coded electronic card access system, which limits access to approved users only. (Please note that support for this instrument will be ending in December 2020.)
