Cell viability of HL-60-cells.

<p>The cells were treated with different ML concentrations (see Tables <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0153825#pone.0153825.t002" target="_blank">2</a> and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0153825#pone.0153825.t003" target="_blank">3</a>) for 30, 60 and 120 minutes. The isolated ML, three viscum extract batches and the viscum extract batch 161 in combination with TT 161 extract batch (25 μg/mL and 35 μg/mL OA) were used. The viability was determined with Annexin V-APC and propidium iodide by flow cytometry. The values are expressed as percentages of the untreated control cells. Error bars represent the standard deviation of n = 2 experiments.
