Figure 2From: Influence of RAR α gene on MDR1 expression and P-glycoprotein function in human leukemic cellsComparison of antigen expression by the parental and RARα infected cell lines. Cells were incubated for 30 min at 4°C in the presence of an appropriate monoclonal antibody. After three washes with PBS, cells were incubated for 30 min at 4°C with goat antimouse IgG labeled with phycoerythrin and then analyzed in flow cytometer (Becton Dickinson).Back to article page
