Fig. 8From: Detection of 8-oxoguanine and apurinic/apyrimidinic sites using a fluorophore-labeled probe with cell-penetrating abilityATP 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. Cells were collected and lysed with 0.5% TCA. ATP levels were analyzed for luciferase activity using a luminometer. Data shown represent the means of 3 individual experimentsBack to article page
