Figure Lengend Snippet: Related to . ( A ) Immunofluorescence study showing colocalization of BG4 (antibody that binds to G4 DNA) and mitochondrial genome. Nucleus from HeLa cells is stained with DAPI (blue color). Mitochondria are stained with MitoTracker green FM and G4 DNA with BG4 (Alexa-Fluor 568), a merged image is shown. A merge of red and green is depicted by Coste’s mask (colocalization is represented as a white dot). The experiments were done independently in HeLa and HEK 293T cells and the quantitation of colocalization of BG4 with MitoTracker is shown in . ( B ) Increasing concentrations (0.2, 0.5, 1, and 2 µg) of purified BG4 was incubated with G-rich ( G1 ) and C-rich ( C1 ) oligomers and products were resolved on 5% native polyacrylamide gel. In each case a lane without protein (lane 1 and 6) served as control. The substrate and the bound complex are marked.
