Figure 1: (A) Phenoloxidase (PO) activity, and (B) respiratory burst (release of superoxide anion) of white shrimp hemocytes incubated with Petalonia binghamiae extract. Cacodylate buffer (CAC) served as background control for PO activity assay, and MHCBSS (modified complete Hank’s balance salt solution) served as background control for RB assay. Each bar represents the mean value from eight shrimp with standard error. Data with different letter significantly differ (p < 0.5) among treatments.
