M.-L. Martin-Magniette, J. Aubert, E. Cabannes, J.-J. Daudin
2005 Bioinformatics  
Motivation: In cDNA microarray experiments all samples are labeled with either Cy3 or Cy5. Systematic and gene-specific dye bias effects have been observed in dual-color experiments.  ...  Methods: The gene-specific dye bias is taken into account using an analysis of variance model. We propose an index, named label bias index, to measure the gene-specific dye bias.  ...  Simon on the paper 'Evaluation of the gene-specific dye-bias in cDNA microarray experiments' BIOINFORMATICS Fig. 1 . 1 Plots of the log-ratios log 2 (R/G): first slide in x-axis and second slide in y-axis  ...
