Figure 2From: Mammosphere culture of metastatic breast cancer cells enriches for tumorigenic breast cancer cellsCD24 expression by pleural effusion cells as detected by antibodies SWA11 and ML5. Cells isolated from pleural effusions were stained with unconjugated SWA11 and ML5, and antibody binding was detected by fluorescein isothiocyanate-conjugated rabbit anti-mouse secondary antibody (see Materials and methods). Filled histograms, 2° antibody only; thin grey line, SWA11; thick black line, ML5. PE, pleural effusion.Back to article page
