FLUORESCENCE ACTIVATED CELL SORTING FACILITY
    The Fluorescence Activated Cell Sorting Facility contains a laser activated, state-of-the-art cell analysis and sorting machine; the BD FACSVantage SE with CloneCyt Plus, DiVa and TurboSort options is one of the most advanced flow cytometers in the world. IN addition, it has two analysis machines: a nine colour (eleven parameter) Dako Cyan flow cytometer and a BD FACSCalibur

BD FACSVantage SE CELL SORTER
The BD FACSVantage SE System is equipped with an air-cooled Spectra-Physics HeNe Laser (633nm) and a water cooled Coherent Enterprise II laser. The Enterprise II is a small frame ion laser that has multiple wavelength outputs, providing simultaneous lines at 488nm and 351-364nm. 
    The BD FACSVantage SE System is able to collect 2 scatter and 8 fluorescent signals per cell and can achieve sort speeds of up to 7,000 cells per second on high speed and up to 25,000 cells per second using the BD TurboSort option in analogue mode. The FACSDiVa option provides zero dead time, allowing faster sorts (up to 60,000 events per second) and higher yields than the standard Vantage SE, and enables 4-way sorting with the QuadraSort functionality. The DiVa option uses matrix algebra for fully independent compensation of all channels. Pulse processing allows the measurement of area, width and ratio of detector pulses, and can be used to detect doublets in DNA analysis or the ratio of two fluorescence signals for use in calcium flux measurements.
   The BD CloneCyt Plus option is able to deposit a predefined number of cells into a wide variety of collection devices such as microscope slides, 96 or 24 well plates. In addition, BD IndexSort™ Technology allows specific information regarding single cells sorted into each well of a 96-well tray to be recorded and linked to clonal expansion. There are many applications for this type of technology, for example, monoclonal antibody production, isolation of gene transduced cells to study gene expression, and PCR at the single cell level.

DAKO CyAn ADP FLOW CYTOMETER
   In 2006, the CGC acquired a nine colour flow cytometric analysis machine, the Dako Cyan flow cytometer. Equipped with three lasers, with excitation wavelengths of 488 nm, 635 nm and 405 nm, the Cyan features a high signal strength solid optical flow cell, full interlaser compensation and analysis rates of up to 50,000 events per second. 
 


BD FACSCalibur FLOW CYTOMETER
    The FACSCalibur is equipped with a 488 argon laser and can measure up to three fluorescent colors, as well as FSC and SSC. The FACSCalibur is engineered with fixed optical, electronic and fluidic components, giving it great stability and ease of use.

FLUORESCENCE MICROSCOPE

    The Fluorescence Activated Cell Sorting Facility also houses a range of other equipment to facilitate the preparation and analysis of cell samples. The Center's fluorescence microscope is an Olympus BX51 inverted microscope with dual photomicroscopy options: the PM-30 automatic photomicrographic system for film based images and the Optronics MagnaFire digital camera for computer based imaging. Viewing options include brightfield, reflected fluorescence, phase contrast (three modes) and DIC (Nomarski). The filter blocks available allow visualisation of FITC, PE, DAPI, Texas Red, Hoechst, PI, Fluo-3, Rhodamine Dil and Ethidium Bromide. The objectives available are: CFI Plan Fluor 4x and Dll 10x, 20x, 40x and 100x.

CELL COUNTER
   A dual threshold Beckman Coulter Z1 cell counter is used to count total blood cell and lymphocyte numbers in blood or experimental samples. Based on the principle of electrolyte impedence, the counter can be used to count leukocyte numbers without plasma membrane lysis.
    A Shandon Cyrotome E Electic Cryostat is available for the preparation of frozen sections
