2D – Plot of minimum value of measured distances between MLL to AF4 and MLL to ENL genes for all cells. Distances are expressed in μm. Vertical and horizontal blue lines symbolize the gene proximity criterion (2 μm) below which genes could be potentially translocated. Values express the percentage of cells in which the distances reported in one axis is smaller than the distance on the other axis. Grey areas correspond to nuclei where only one of gene could be translocated.
