Figure 1

Cell viability after 16 h exposure to ciguatoxin (CTX)-negative fish extracts without the clean-up step: Pagrus pagrus (NC1); Epinephelus marginatus (NC2); Pomatomus saltatrix (NC3); Seriola dumerili (NC4) and Acantocybium solandri (NC5). Black bars show cell viability for a tissue equivalent dose of 25 mg and gray bars represent the ten-fold diluted fish extracts (2.5 mg two equivalent tissue (TE) dose). Dotted line represents 90% of cell viability, limit of non-specific toxic effects. Each extract was analyzed in triplicate and error bars represent assay variability.
