 AB    A three-color flow cytometric determination of CD4 T-lymphocytes on
       whole blood specimens from AIDS patients which contain a high proportion
       of non-lymphocyte elements is described. Peripheral blood cells were
       stained by a three-color method using monoclonal antibodies conjugated
       respectively with fluorescein isothiocyanate (FITC)-CD3, phycoerythrin
       (PE)-CD4 and peridinin chlorophyll protein (PerCP)-CD45. CD45 stains all
       leukocytes with the highest fluorescence expression of CD45 antigen in
       lymphocytes. By combining light scatter with CD45 in the fluorescence 3
       (FL3) channel, a light scattering window can be drawn to include almost
       all bright CD45 lymphocytes. This live gate of lymphocytes was then
       acquired and analysed simultaneously using other irrelevant two-color
       (FITC/PE) antibodies of CD3 and CD4 in the FITC and PE channels,
       respectively. This method is easy and straightforward, and gives
       successful analysis of CD4 T-lymphocytes in AIDS blood specimens
       contaminated with an unusually large number of non-lymphocytic cells.
