Figure 1.

Effect of C-phycocyanin in microglia cell viability. Microglia were cultured overnight in medium containing 10% of serum, which was replaced with serum-free medium before exposure to C-PC (1–300 μg/mL) for 16 h. At the end of incubation, SRB assay was used to measure cell viability. Results are expressed as percentage of cell viability relative to control cells. Data are means ± SEM of 3 independent experiments. ** p ˂ 0.01 versus control cells (dashed line). One-way ANOVA followed by Holm–Sidak’s test.
