1. FLOW CYTOMETRY FACILITY


Flow cytometry is a powerful technique for the analysis of multiple parameters of individual cells within heterogeneous populations. The flow cytometers performs this analysis by passing thousands of cells per second through a laser beam and capturing the light that emerges from each cell as it passes through. The data gathered can be analyzed statistically by flow cytometry softwares to report cellular characteristics such as:
 
•    Cell size (FSC)
•    Cell complexity (SSC)
•    Fluorescence

3. APPLICATIONS


Flow cytometers have the ability to measure multiple celular parameters and markers of a large number of cells at a rapid rate. So the applications of flow cytometry are numerous, and this has led to the widespread use of these instruments in biological research.
The main applications that we have developed in the center are:
 
•    Cell viability assays
•    Membrane potencial
•    Inmunophenotyping
•    Cell cycle analysis
•    Apoptosis and necrosis
•    Cell sorting
      -    Stem cells (mouse)
      -    Cell lines
      -    Drosophila discs cells (eyes and wings)
      -    Hematopoietic cells (mouse blood, kidney, liver, bone marrow, spleen, thymus)
