Resveratrol Can Be Stable in a Medium Containing Fetal Bovine Serum with Pyruvate but Shortens the Lifespan of Human Fibroblastic Hs68 Cells

Figure 2

Effect of pyruvate or catalase to potentiate the superoxide dismutase (SOD) activity. (a) SOD (1.25 U/mL) was incubated with or without catalase (100 U/mL) or pyruvate (1 mM) in a microplate in a total volume of 200 μL, as described in Materials and Methods. SOD activities are expressed as percent of inhibition. (b) Effect of pyruvate on the SOD activity of fetal bovine serum (FBS). FBS (40 μL) was incubated with pyruvate (1 mM) in a microplate at a total volume of 200 μL, as described in Materials and Methods. SOD activities are expressed as U/mL. Values (mean ± standard deviation, ) without a common letter are significantly different ().
