Our mission is to provide complete flow cytometry analysis and cell sorting services in terms of experimental design, instrumentation, training, technical assistance and scientific guidance.
The fee-for-service LDI Flow Cytometry Facility provides researchers and clinicians with instrumentation, scientific expertise and guidance. . It consists of three flow cytometry analyzers and two cell sorters. The Sony Biotechnology’s flagship ID7000 Spectral Cell Analyzer is our latest acquisition. It is one of the most advanced full spectrum flow cytometers on the market and it allows researchers to perform 44-colour plus assays. The facility also makes use of two conventional flow cytometers: BD LSR Fortessa and BD FACSCanto II. The FACSAria IIu and FACSAria Fusion cell sorters are available to carry out both BSL1 and BLS2 cloning and bulk cell sorting assays. Finally, the CellDrop FL cell counter (Denovix) allows accurate cell counting and cell size determination. . Several flow cytometry data analysis stations are available.
With an array of lasers, prisms, mirrors and filters, flow cytometry instruments enable us to look at several physical and fluorescent parameters of a single cell. These physical and fluorescent parameters are analyzed simultaneously, and since flow cytometers can analyze tens of thousands of cells per second, large populations of cells can easily be quantitatively characterized at single cell resolution. It is this multiplexing capability that makes flow cytometry an extremely versatile and powerful tool for both researchers and clinicians. In addition, fluorescence activated cell sorters can physically separate these populations in different vessels or deposit single cells into a multi-well plate for cloning.
Flow cytometry (FCM) is a versatile technology, which allows for quantification of fluorescence and structural features of particles (most commonly cells). FCM analyzers provide rapid quantitative analysis of particles in suspension or soluble proteins from serum, fractioned cells, trypsinized cells or dissociated tissue. Researchers and clinicians can obtain several statistics on a single cell and population level. Cell sorters can also analyze particles and, in addition, can physically separate cells of interest at high purity for downstream assays. A non-exhaustive list of different flow cytometry assays is listed below.
The advantage of using FCM is that it is an extremely fast procedure and a relatively small quantity of sample is needed. Sample processing, acquisition, analysis and data reporting can be performed in just one day. Furthermore, in multiparameter FCM, several fluorescent parameters or colors are analyzed simultaneously. We can for example identify the phenotype and ascertain viability, vitality, proliferative capacity and cell cycle state of each cell. Therefore, since millions of cells can be quickly analyzed, we can identify extremely rare cell populations and also obtain population statistics with greater accuracy.
