Fig. 4From: Exploring new potential role of DDB2 by host cell reactivation assay in human tumorigenic cellsDDB2-PCNA binding influences the late phase of repair process. Representative analysis obtained from transfected and irradiated HeLa cells using immunofluorescence microscope (a). Scale bar = 20 μm. In b confocal images and analysis are reported. The peaks exemplify the co-localization studies between DDB2 and XPG proteins. Data are at least from three independent experimentsBack to article page
