MTS metabolism in Hela cells after treatment with different doses of venom (50-400 μg/100 μL of medium), positive control (CFF, cyclophosphamide 400 μg/100 μL) and negative control (CTRL–). Optical density (OD) was read at 490 nm, the data were plotted according to the mean and SD. Treatment means differed significantly with respect to the positive control but not for the negative control (p < 0.05).
