The immunotype of acute leukaemia in Kelantan as determined by flow cytometry

The present study reports the total number of acute leukaemias diagnosed in Kelantan over a period of 36 months by morphology, cytochemistry and flow cytometry or immunophenotype using ten monoclonal antibodies (to cell surface CD or HLA-DR antigens) coupled with fluorescein isothiocyanate (FITC)&a...
