FIGURE 3. Flow cytometric analysis of blood collected at various time points from SCID mice injected intravenously with 20 x 106 Ph+ ALL cells on day 0. Groups of mice (n = 8) were treated intravenously with CLB-CD19 antibody (A) or saline vehicle (B) on day 26. The mean ± SD proportion of human (open bars) and murine (hatched bars) cells expressing human or murine CD45, respectively, was expressed as percentage of total CD45+ white blood cells at each time point.
