Figure 3. Comparison of D407 to ARPE19 cells using Affymetrix microarrays

The comparison of the D407 cell line and the ARPE19 cell using the Affymetrix microarray platform is illustrated. The average of three separate experiments is shown in A. The HG-U95Av2 microarray chip was used for the data represented in B and C, while the HG-U133A chip was used for the data in D. All of the data is normalized and scaled to allow for between experiment comparisons. The average of the three experiments was divided into quartiles and colored. Notice the overall agreement between the distributions of the signal intensities across the different individual experiments. The data is scaled as in Figure 1.
