Apoptosis assay HeLa cells after exposure to TsV and z-VAD-fmk. HeLa cells treated with 250μg/mL TsV with the caspase inhibitor. Annexin−/PI−(Q4), viable cells; Annexin+/PI-(Q3), cells undergoing apoptosis; Annexin+/PI+(Q2), cells that are in end-stage apoptosis or are already dead; Annexin−/PI+(Q1), cells that are in necrosis.
