Analysis of SHIP and CD34 expression on AML by flow cytometry. Several AML samples were analyzed for coexpression of SHIP and CD34. The AML shown expressed high levels of both proteins. The upper panel shows the single-parameter analysis of SHIP relative to a control rabbit Ig fraction; the lower two panels show two-parameter analysis of CD34 versus control Ig (left) and CD34 versus SHIP expression (right) in the same AML cells.
