Figure 1 From: Universal Reference RNA as a standard for microarray experiments Microarray experimental design: Comparison of gene expression in two human cell lines using UHRR as a common reference sample. Total RNA isolated from human brain and testis cell lines were reverse-transcribed to cDNA and labeled with Cy5. UHRR was reverse-transcribed to reference cDNA and labeled with Cy3. Each Cy5-labeled cDNA was co-hybridized with Cy3-labeled reference cDNA on microarrays and data analyzed as described in Material and Methods.Back to article page
