Flow cytometry studies optical parameters emitted by particles (cells, cell fractions). Flow cytometers can study a series of parameters of individual particles simultaneously, quickly and on a large number of individualized particles in suspension. Flow cytometers use lasers as a source of light excitement; therefore, it must be possible to mark the particles with one or more fluorescent substances. Information is also collected regarding the size and structural complexity of each particle. This multiparameter study of each particle enables us to analyse subpopulations in complex samples through electronic sorting. Some cytometers are also equipped with sorting and collection modules for particles of interest.
The most important applications of flow cytometry include those relating to the study of cell surface receptors, nuclear and cytoplasmic antigens, DNA content, enzyme activity, cell integrity and membrane permeability and calcium flows.
The Unit currently hosts five analyzers and two sorters, and is therewith the largest Becton Dickinson site in Spain. The sorters are operated by the facility personnel, who also support the users in experimental design and data analysis. The analyzers are operated by the users themselves, after they have been trained. The facility personnel helps with the experimental design and supervises and monitors the experiments when necessary.

New technology acquisition:
New SP6800 Spectral Analyzer (Sony Biotechnology) has been acquired to cover advanced multicolour flow cytometry assays. This new technology facilitates the access to complex phenotype analysis while managing up to 34 fluorescences at the same time. Also simplifies the access to complex multicolor panel by eliminating conventional filters and compensation.
Flow Karyotyping for chromosome sorting was implemented in our facility to isolate chromosomes for chromosome sequencing. Additionally, this methodology allows the detection of numerical and structural chromosome aberrations. Chromosomes of a single type can be purified facilitating gene mapping or production of chromosome-specific recombinant DNA libraries.
Single Virus Sorting has been developed in our facility to isolate single virus. Single virus isolation allows the access to genome of single virus for sequencing. Single Virus Genomics enable the discovery of some of the likely most abundant and ecologically relevant marine viral species. The method could be used to study other biological entities into different ecosystems.
