Additional file 1: Figure S1. Extended radiosensitivity testing on ultra-low passage GBM cell lines. Representative images of 2D-cultured GBM cells (GBM03, GBM06, GBM14, GBM15) stained with anti-H2A.X Phospho (Ser139) [red], treated with 5 nM MitA or left untreated with [+] and without [-] irradiation. Scale bar as indicated: 50 µm. Nuclei were counterstained with DAPI. Images were taken on a Zeiss Elyra 7 Confocal Laser Microscope. Representative images of n = 3 independent experiments.
