Mutagenicity of the sample (0.1 mL) of supernatant obtained from MX solution (0–5 μM) treated with 10 mg/0.1 mL of GP (circle) or WP (triangle, dashed line), or no-powder control (NP, square). MX was dissolved in buffer (a) or DMSO (b). The experiment was repeated twice, and the error bar represents the SD (n = 3)
