The lowest nontoxic concentration of SFE that provided maximum protection was 500 μg/ml and, therefore, it was chosen for subsequent experiments to study the protective effect of SFE on tBHP-induced GSH depletion.
However every complex, at its maximum nontoxic level showed excellent staining ability for both plant and rat peritoneal cells.
GLAB significantly suppressed lipid accumulation in 3T3-L1 cells in a nontoxic concentration.
Nontoxic concentration of MPA (10 μM) reduced ≥99.9% CHIKV titre in vero cells.
Although, the maximum nontoxic dose of Pb blood levels has not been established, there is increasing evidence that even previously considered nontoxic Pb levels increase morbility and mortality rates in general population [ 43].
Both V79 and As/R28A cells (an arsenite-resistant Chinese hamster V79 cell variant) show increased resistance to toxic concentrations of arsenite after pretreatment with a nontoxic concentration.
First, the optimal, nontoxic concentration of Tet was estimated by treating cells with the increasing concentrations of the drug and evaluating cell survival after 24 hours.
Absence of hsp70 expression in larvae exposed to 0.1 micro L/mL of the effluent indicated that this is the highest nontoxic concentration for Drosophila.
For potentiation experiments, cells were preincubated with a relatively nontoxic concentration of APE1 inhibitor for 24 h and then exposed to MMS, temozolomide or doxorubicin.
Azadi et al. [ 58] reported that the nontoxic concentration of chloroformic extract of Allium hirtifolium to normal mouse fibroblast cell line L929 was 1.00 mg/mL.
