The Cytometry Service (SGC) is a common research platform of open use to all members of the Institute (Cancer Research Centre) as well as to other external research and clinical groups. It is aimed at supporting research and education in cytometry. The most relevant activities include cell analysis and sorting for research purposes with more than 50 different techniques being currently set up and available in the area of immunophenotyping, cell cycle analysis, apoptosis, drug resistance and screening, quantification of phosphorylated proteins and their associated intracellular signalling pathways, among others. In addition, it provides tests to support the diagnosis of cancer acting as a common platform for the immunophenotypic diagnosis of leukemias and lymphomas for the Spanish RTICC from the Instituto de Salud Carlos III. In parallel, at the SGC there are several ongoing technologically oriented research projects.

Finally, the SGC has an important role in education in Cytometry with more than 35 researches from all over the world being trained during the last year, and more than 350 in the last 15 years.

ISO Certifications: The SGC is certified with the ISO-9001:2000, applied to «Molecular, Genetic and immunophenotypic studies
to support the diagnosis and monitoring of haematological malignancies, using flow cytometry, FISH and molecular biology» since the 3rd of August 2007.
