Figure 3

Relative metabolic activity of L929 cells (resazurin assay) after 24 h incubation with extracts of Zn_SPS. Three replicates 1–3 were used. Extracts were prepared in medium either with 5% or with 10% FBS. Sole extraction medium served as a control (unaffected cells which metabolic activity was taken as 100%). Numbers above the columns stand for the concentration of measured Zn in µM. The dashed line stands for the normative limit of 70% metabolic activity of the control. Error bars stand for the standard error deviation of six measurements. Significance codes according to p value: 0 ‘***’0.001 ‘**’0.01 ‘*’0.05 (two-sample t-test).
