Figure 3From: Loss of Parp-1 affects gene expression profile in a genome-wide manner in ES cells and liver cellsConfirmation of differentially expressed genes in microarray analysis by northern blot analysis (A), and functional categorization of up- and down-regulated genes (B). Ten micrograms of total RNA were used for northern blot analysis in (A). Copy numbers were calculated from the radioactivities of the probe control.Back to article page
