CD4 and CD8 distribution on total thymocytes and on 9-Oacetyl+ cells. Three-color flow cytometry was done after staining with CHE-FcD, anti-CD4, and anti-CD8. The 9-O-acetyl positive cells were gated to obtain a selective CD4/CD8 profile. Since CD8 SP and CD4− CD8− DN cells constitute a low percentage of total thymocytes, 100,000 total events were acquired to analyze the small percentage of total 9-Oacetyl+ thymocytes.
