Fig. 3From: Rapid assessment of 3-dimensional intra-tumor heterogeneity through cycling temperature capillary electrophoresis2D and 3D heatmaps of allele frequency and distribution in tumor tissue. 2D heatmaps of Trp53 (A) and Kras (C) mutant allele frequencies in independent z-planes of mouse mammary gland tumors. 3D heatmaps of the same Trp53 (B) and Kras (D) mutant allele frequencies were generated from the independent z-planes of mouse mammary gland tumors. Interactive 3D heatmaps are available in Additional file 5: Figs. S2 and S3Back to article page
