All IGR transcripts identified by cDNA sequencing (sRNA and mRNAs) within a 400 kbp fragment of the chromosome (11.700–407.000) have been analyzedby northern hybridizations. Besides the genomic context and the length determined from cDNA sequencing and northern results, the respective differentialtranscription calculated from the normalized number of cDNA reads and from the northern analysis (normalized in respect to the 5S rRNA transcript level) aregiven. n.d., not detected.
