Primary screen for activators of FANCD2 mono-ubiquitination in the absence of FANC-C -E -F. (a) All compounds screened in duplicate plotted as Z scores and presented on a per library representation. (b) Nine-point titration of 47 activator hits. (c) Area under curve plot calculated from the curves in 3b, demonstrating activation potency for each compound. (d) Cropped images from western blot analysis of 4 activator hits for an effect on the FANCD2 mono-ubiquitination assay with recombinant protein. Positive (Complete Core Complex) and negative (DMSO) controls are shown on the far-left panel. The four activator hits from the secondary screen were analysed with FANCD2-ubiquitination assay (without FANC-E-F) visualised on western blot by probing with streptavidin to detect biotinylated-ubiquitin. Three concentrations of the compounds were used; 1 µM, 10 µM and 100 µM.
