FACS analysis and confocal staining. FACS analysis of OE33 cells incubated with SNF-Cy5.5, SNF-Cy5.5 + unlabeled SNF and PBS (A). confocal immunofluorescence of SNF-Cy5.5 location (× 400). Cells were stained with DAPI (nuclear staining) colored in green, and Cy5.5-GX1 colored in red (B). The SNF-Cy5.5 binds to the plasma membrane of OE33 cells but little binding to that of the control cells and Het-1A or that of OE33 blocked by unlabeled SNF
