Expression of CD9 and CD138 cell surface markers on PWM-treated MER myeloma cells.

Top panels represent untreated MER cells. The lower panels represent MER cells treated with 1% PWM for 3 days. In the left panels, MER cells are labeled with the anti-CD138 mAb BB4. In the right panels, MER cells are labeled with the anti-CD9 mAb ALB6. The curve on the left in each panel is IgG1 control antibody, and the curve on the right in each panel represents the expression of the cell surface marker of interest.
