The percentages of CD95 T cells were obtained by staining PBMCs with the following combinations of FITC-, PE-, and CyChrome-conjugated mAbs: CD95, CD4 or CD8, and CD3. The percentages of CD45RA+CD62L+ T cells were obtained by staining PBMCs with CD45RA, CD62L and CD4, or CD8 mAbs. Data from 10 donors, 18-100 years of age, are shown.
