Figure 4: Impact of H2O2 on cellular viability is influenced by PL in culture. (a) Metabolic activity of cultures measured by PrestoBlue conversion 6 hrs after the treatment with H2O2. Data are expressed as mean + SD, , derived from 2 experiments. (b) Automatic viable cell counts after 6 hrs of treatment. Data were normalised to median value of control samples and shown as mean + SD, . To determine significant results, the unpaired -test was performed (; ; ; ). CM, treatment performed in complete medium; BM, treatment performed in basal medium.
