Figure 4. Flow cytometric analysis of phaseolus vulgaris agglutinin binding on the surface of human uveal (92–1, Mel202) and cutaneous melanoma (FM55P, IGR-39) cells. A: Histogram of fluorescence intensity with or without fluorescein isothiocyanate (FITC)-conjugated phaseolus vulgaris agglutinin. B: Quantification of data from flow cytometric analyses. Fluorescence intensity relative to negative control, representing means from three pooled experiments. Asterisk (*) indicates p<0.05.
