The CD164(103B2/9E10) epitope is expressed on myelomonocytic cells in bone marrow. Representative dot plots from one of two separate experiments showing Ficoll separated bone marrow mononuclear cells labeled with the 103B2/9E10 MoAb or with an IgG₃ negative control MoAb plus CD34-PerCP and with the FITC-conjugated MoAbs indicated before counterstaining with PE anti-mouse IgG₃ and analysis on the FACSCalibur. Gates were set to exclude the CD34⁺ cell population before myelomonocytic cell analysis.
