Anti-CCR5 staining partially colocalizes with GM1.

CEM-R5 cells were stained with CT-B–AF594 followed by staining with the anti-CCR5 mAb, CTC5, in combination with GAM-AF488 (A,B). AF488 fluorescence is shown in green and CT-B–AF596 fluorescence is shown in red. Panel A represents a subpopulation of capped cells observed within the stained cells, whereas panel B represents a subpopulation of noncapped cells. As in Figure 6, colocalization is indicated by yellow and/or orange color. Magnification, × 500.
