Figure Lengend Snippet: Effect of heparin loading on the binding capacity of heparin-immobilized microspheres to human aFGF (30 ng/mL). The fluorescence signal on the beads was developed by incubating the beads with PE-labeled antibody and measured on the BD FACSArray flow cytometer. The MFI values were significantly different for the microspheres with varying heparin loading amounts at the 95% confidence level (one-way ANOVA). The error bars represent the standard deviations of the mean intensities based on three independent experiments.

Figure Lengend Snippet: Effect of free heparin on the interaction between the cytokine, CCL2 (■) or aFGF (▲), and the heparin-immobilized microspheres. The fluorescence signal on the beads was developed by incubating the beads with corresponding PE-labeled antibody and measured on the BD FACSArray flow cytometer. The error bars represent the standard deviations of the mean intensities based on three independent experiments.

Figure Lengend Snippet: Binding of cytokines, (a) aFGF, (b) CCL2, (c) VEGF, and (d) CCL5, onto the heparin-immobilized microspheres (■) and the acetylated amino microspheres (□). The fluorescence signal on the beads was developed by incubating the beads with corresponding PE-labeled antibody and measured on the BD FACSArray flow cytometer (aFGF and CCL2) or the Luminex system (VEGF and CCL5). Inset: binding of each cytokine to the heparin-immobilized microspheres with background binding to the acetylated amino microspheres subtracted. The error bars represent the standard deviations of the mean intensities based on three independent experiments.

Figure Lengend Snippet: Binding kinetics of cytokines, aFGF (■), VEGF (●), CCL2 (▲), and CCL5 (▼), onto the heparin-immobilized microspheres. % Bound cytokine was calculated as the mass ratio of captured cytokine to the total cytokine initially added. The error bars represent the standard deviations of the mean values based on three independent experiments.
