Figure 3From: A qualitative assessment of direct-labeled cDNA products prior to microarray analysisPractical application of the Cy5-cDNA Bioanalyzer assay. (A) Overlayed electropherogram image of Cy5-dUTP labeled cDNA obtained from control RNAs (MCF7 and HACAT, red and blue traces, respectively) and from test samples (Test #1 and Test #2, brown and purple traces respectively). First and second sharp peaks are as described in legend for Figure 1. (B) Average microarray intensity for MCF7, Test 1 and Test 2. Error bar is standard error from three arrays. Test samples were hybridized to only one microarray each.Back to article page
