Figure 1From: Intracellular coexpression of CXC- and CC– chemokine receptors and their ligands in human melanoma cell lines and dynamic variations after xenotransplantation Surface expression of chemokine receptors. Representative examples for the quantification of chemokine receptors surface expression by flow cytometry are shown. Overlaid histograms of PE fluorescence of specific anti-receptor monoclonal antibody (continuous red line) and correspondent isotypic control (discontinuous black line) show the control Hut-78 cell line with a high percentage of CXCR3+ cells (A), WM-115 with no expression of CXCR4 (B) and IGR-39 with a small subpopulation of CXCR7+ cells (C), which is further illustrated in a biparametric dotplot of FS vs PE fluorescence (D).Back to article page
