Cell Sorters

The sorters in our Facility make use of electrostatic deflection of droplets. Fluid containing particles passes through a nozzle and a stream emerges into the air. The fluid stream breaks up into droplets- with the aim being the generation of droplets big enough to contain one cell in each drop. To do this, the stream is vibrated at a specific frequency and pressure to separate it into droplets. These droplets are then charged or not depending upon the fluorescent profile of the cell(s) within. The drops pass through an electric field allowing electrostatic or droplet deflection which sends the charged drops of interest into the collection vessel. Unsorted droplets go into the waste.

BD Aria III | Instrument Configuration

The BD FACSAria III cell sorter is the high-speed benchtop digital flow cytometer. It is equipped with five spatially separated air-cooled lasers - 488 nm, 633 nm, 561 nm, 375 nm, and 405 nm. The near UV (375 nm) laser uses the same path as the violet (405 nm) laser and cannot be used simultaneously.

Most cell types can be accommodated with the use of 130, 100, 85, or 70-micron nozzles. Sorting can be performed into two or four tubes with a speed of up to 35,000 events/sec. The Automated Cell Deposition Unit (ACDU) makes it possible to sort individual cells into multi-well plates (up to 96 well), PCR tubes, or microscope slides. The instrument is also equipped with Aerosol Management Option (AMO), a device that traps aerosolized particles. The system operates on a PC-based Windows platform using BD FACSDiva software.

BD Aria III BSL2 (16-color) | Instrument Configuration

The BD FACSAria III cell sorter is the high-speed benchtop digital flow cytometer. It is equipped with five spatially separated air-cooled lasers - 488 nm, 633 nm, 561 nm, 375 nm, and 405 nm. The near UV (375 nm) laser uses the same path as the violet (405 nm) laser and cannot be used simultaneously.

The BSL2 FACSAria III is enclosed by the BioProtect IV ClassII Type A2 biosafety cabinet from Baker Company. The cabinet provides HEPA filtration and airflow control to maximize the protection of the operators from potentially hazardous samples.

Sony MA900 (12-color)

The MA900 system includes a patented microfluidic chip-based design, comprehensive fluidic controls, and advanced automation. It is equipped with 4 excitation lasers - 488 nm, 405 nm, 561 nm, and 638 nm - on two beam spots. Free-form PMTs enable the detection of fluorescence signals from each beam spot, allowing the detection of 12 fluorescence parameters and 2 scatter parameters. This sorter is available for user training and operation.

The MA900 has microfluidic chips available for 100 or 70-micron sorting. Sorting can be performed into two or four tubes or into multi-well plates (up to 384 well) or PCR tubes. Index sorting is available in multi-well plates. Index sorting software records the X and Y coordinates of each event sorted into a multiwell device. This software enables you to track the scatter and fluorescence intensity of individual cells sorted in each well. The instrument is also equipped with Aerosol Management Option (AMO), a device that traps aerosolized particles.

Cell Analyzers

Our Flow Cytometry analysers are based on differential pressure and are designed to analyze cells at a high rate (up to ca 10,000 - 40,000 cells (events) per second on the perfect single cell sample).Several parameters can be measured on individual cells within a few minutes. This is the power of flow cytometry. The properties measured include a particle's relative size, granularity, and relative fluorescence intensity (please see the individual machines for the number of fluorochromes they can analysis in one cell/particle). Any suspended particle or cell from 0.2-70 micrometers in size is suitable for analysis. Larger or smaller particles require specialized cytometers/conditions.
