A representative FACS profile of normal adult human lin− bone marrow cells after staining with CD34-FITC and CD38-PE. Lineage marker-positive cells were removed using a StemSep column and the flow through (lin−) cells were then labeled. Dead (PI+) cells were excluded from the analysis. The left panel shows the level of nonspecific staining obtained with isotype control antibodies. The right panel shows the result obtained after staining with anti-CD34-FITC and anti-CD38-PE.
