MARSAN SUAREZ, Vianed; DEL VALLE PEREZ, Lázaro O; DIAZ DOMINGUEZ, Gabriela  e  MACIAS ABRAHAM, Consuelo. Methodology and applications of flow cytometry for immunophenotyping of acute leukemias. Rev Cubana Hematol Inmunol Hemoter [online]. 2015, vol.31, n.3, pp. 242-253. ISSN 1561-2996.

Flow cytometry (FCM) is an advanced, highly sensitive and automated technique used for immunophenotyping of normal and leukemic cells. The main methodological aspects to consider for better development and interpretation of immunophenotyping by FCM are shown in this article. Among them are: type, quantity, storage and transportation of the sample, use of anticoagulants, use of monoclonal antibodies and fluorochromes, erythrocyte lysate, cell attachment, calibration and auto-fluorescence compensation. Finally, the main applications of this methodology are given for defining the state of leukemic cell maturation, acute leukemias rank in different immunological subtypes, poor prognosis subgroups and to identify and detect aberrant phenotypes, which are useful for the diagnosis of minimal residual disease, allowing to stratify patients into different risk groups and thus to identify the anti-leukemic treatment.
