Gene expression analysis from Ribo-Zero™-treated RNA

The Ribo-Zero™ rRNA Removal Kit (Human/Mouse/Rat) was compared to a competitive kit's performance in removing rRNA from total RNA samples that were used for RNA-Seq. Both kits performed equivalently for intact RNA samples, while the Ribo-Zero Kit performed better than the competitive kit for partially degraded RNA samples.

Consistent gene expression data from Ribo-Zero™-treated RNA. Intact and partially degraded Universal Human Reference RNA (UHRR) was treated with either the Ribo-Zero Kit or a competitive kit. The rRNA-depleted RNAs were then used to prepare cDNA libraries that were sequenced on an Illumina® GAII sequencer.  A) Number of genes detected in libraries prepared from intact or partially degraded, rRNA-depleted UHRR. B) Correlation of expression levels for intact RNA. C) Correlation of expression levels for partially fragmented RNA. RPKM, reads per kilobase of exon model per million mapped reads.
