This unit presents basic techniques for immunophenotyping by flow cytometry, direct using a conjugated monoclonal antibody and indirect using an unconjugated primary antibody followed by a conjugated secondary antibody. Combinations of these methods are described for two-, three-, and four-color staining. Analysis of data acquired from cells stained by these procedures is detailed. A procedure ...

OBJECTIVE Diagnostic hematopathology depends on the applications of flow cytometric immunophenotyping and immunohistochemical immunophenotyping combined with the cytomorphology and histologic features of each case. Select cases may require additional ancillary cytogenetic and molecular studies for diagnosis. The purpose of this review is to focus on the applications of flow cytometric and immun...

Immunophenotyping refers to the application of antibodies specific for differentiation antigens of leukocytes to identify lineages of these cells present in reactive (inflammatory) or neoplastic diseases involving the immune system. Immunophenotyping is an objective adjunct to conventional morphologic assessment. Immunophenotyping can be performed on fluids (such as blood, bone marrow and tissu...

Functional immunophenotyping of immune cells is a promising method for diagnosis of immune dysfunctions. In this study, an integrated microfluidic immunophenotyping device was developed that could achieve rapid and efficient isolation, enrichment, stimulation and functional immunophenotyping of subpopulations of immune cells directly from blood specimens. This new microfluidic immunophenotyping...

This study evaluated the contributing roles of flow cytometric immunophenotyping of blood and bone marrow and immunohistochemical paraffin section staining of bone marrow biopsies in the staging of B-cell malignant lymphoma. Flow immunophenotyping was performed on a marrow specimen in 175 cases; a corresponding blood specimen was also immunophenotyped in 135 of these cases. Morphologic marrow i...

background: myelodysplastic syndrome is a mixed clonal disorder of bone marrow progenitor cells. understanding the pattern of the different lineage-specific, immature, and mature markers in myelodysplastic syndrome will help in setting-up the frame of reference to diagnose. patients and methods: we compared 60 bone marrow samples from 30 newly-diagnosed patients with myelodysplastic syndrome an...
