Fig. 2From: Detection of 8-oxoguanine and apurinic/apyrimidinic sites using a fluorophore-labeled probe with cell-penetrating abilityCell viability assay of the TAT-S3 probe on HeLa cells. HeLa cells were treated with the indicated concentrations of the TAT-S3 probe for 24 h. Cell viability was determined using an MTT assay. Significant differences are indicated as *p < 0.01. Data shown represent the means of 3 individual experiments. * p < 0.01 compared with untreated groupBack to article page
