Fig. 1. Comparison of the expression profiles of transcripts by Northern and oligonucleotide microarray hybridization. Northern hybridization was performed with probes for the indicated transcripts on RNAs obtained in a representative replicate of the three experiments performed and used for microarray expression analysis. The hybridization signal obtained for ACTB was performed to control for loading. The log-transformed expression profile obtained for the respective experiment for each transcript using oligonucleotide microarrays is shown.
