Figure 1.

Performance evaluation of five rRNA depletion methods. (a) Shown is the distribution of RNA-seq reads aligning to protein-coding sequences (CDS; blue), rRNA (red), and other regions (tRNA, non-coding RNA, small RNA, and intergenic regions; gray) for undepleted total RNA (top) and five rRNA depletion protocols. (b) The lengths of the black bars represent the coefficient of determination (R2) for RPKM values before and after rRNA depletion using different rRNA-depletion methods. Ribo-Zero, normalization using duplex-specific nuclease (DSN) and Ovation were tested on a 1:1:1 pool (by mass) of total RNA prepared from P. marinus, E. coli, and R. sphaeroides. MICROBExpress and mRNA-ONLY were performed on individual RNA preparations without pooling.
