FIG 1.
Surface expression of known KSHV receptors on Caki-1 and HeLa cells. (A and C) Live Caki-1 (A) and HeLa (C) cells were immunostained for surface expression of known KSHV receptors and analyzed by flow cytometry. Gray histograms represent the isotype control. (B and D) The mean fluorescence intensity (MFI) of each receptor stain was divided by that of the appropriate primary antibody isotype control and plotted as summarizing bar graphs. ND, not detected.
