Flow cytometric analysis of FDB2 cells expressing FLAG-tagged hβc subunits.

After culture for 7 days in the presence of the indicated growth factors or in the absence of growth factors (no factor), FDB2 cells expressing the indicated FLAG-tagged hβc proteins were stained with rat monoclonal antibodies specific for the indicated surface antigens (solid lines) or an irrelevant isotype control (dashed lines). Scatter profiles are shown as contour maps.
