Figure 7. Effects of native β-D-glucan and three β-D-glucan phosphates, GP-2, GP-4, and GP-5, on NO secretion by RAW264.7 cells.

RAW264.7 cells were treated as Fig. 5. After incubation, the NO concentrations in the supernatant were detected by the A₅₄₀ value after reacting with Griess reagent. The data represent the means ± SD. *p<0.05, **p<0.01 compared with control. Each point represents the average of three independent experiments.
