Real-time PCR validation of differentially expressed genes in the 3 versus 5 dpf zebrafish eyes data set. These genes can only be detected by remapping using the multiple source database, UCSC. (A) Signal intensities from microarray data. (B) Real-time PCR results depicted as relative abundance compared to lowest abundance sample. *: p-value < 0.05. **: p-value < 0.01.
