Fig. 4From: Reliable gene expression profiling of formalin-fixed paraffin-embedded breast cancer tissue (FFPE) using cDNA-mediated annealing, extension, selection, and ligation whole-genome (DASL WG) assayHierarchical clustering of FF and FFPE samples assessed using the DASL WG assay, and of FF samples assessed using the Illumina BeadArray. This shows significant clustering of FF and FFPE samples, regardless of whether the DASL WG or the BeadArray (indicated by number only) are usedBack to article page
