Table 3. CCK-8 Proliferation Assay of Saos-2 Cultured on Different Concentrations of Samples after Incubation for 7 days^a.

^aThe displayed average values are for the viability rate calculated as the percentage ratio of the absorbance at wavelength 480 nm for the samples to the corresponding absorbance for control cells incubated without samples in the same microplate. The standard deviation varied between 5 and 7%. Cell death was the main regime in the values presented in red as per the color observations.
