Figure 1From: High-throughput analysis of candidate imprinted genes and allele-specific gene expression in the human term placentaCorrelation of Sequenom and Illumina allele quantification. Pearson's correlation coefficient (r) is calculated for the allele-specific quantification on the two platforms and plotted against cDNA intensity (average log2 fluorescence for the 23 placentas) on Illumina. The correlation drops when cDNA average intensity is lower than the 11.25 cut-off (dashed red line).Back to article page
