Figure 2From: The radiosensitization effects of Endostar on human lung squamous cancer cells H-520Clonogenic survival of H-520 cells after different treatments including irradiation with or without ES. H-520 cells were treated with 200 μg/mL ES for 24 h and then washed. These ES-treated or control H520 cells received 0-10Gy radiation and cloning formation was detected by 21 days after irradiation. Data were a summary of three experiments.Back to article page
