KAPA RNA s provide a streamlined, versatile core library construction solution, that may be combined with various enrichment options, either before or after library preparation. Depending on the sample type and experimental design, unwanted and/or other s (e.g., globin in blood samples) may be enzymatically depleted using KAPA RiboErase (HMR) s; or poly(a)-tailed mrna may be selected with KAPA mrna Capture s prior to library construction. Alternatively, total RNA libraries may be prepared and coding or non-coding content selected by hybridization capture, using SeqCap probes and the HyperCap Workflow. HMR: human, mouse and rat. User-supplied probe sets may be used to deplete additional s from these species, or s from other species. All KAPA s contain KAPA Pure Beads for reaction cleanups. *Protocols in development. The current supported workflow for target enrichment after cdna library preparation is based on the SeqCap RNA Enrichment System. 2

The novel chemistry employed in KAPA RNA s allows for fewer enzymatic and cleanup steps, which reduces hands-on and overall library prep time. RNA depletion with KAPA RiboErase (HMR) or KAPA RiboErase (HMR) Globin s adds approximately 2. hours to the overall workflow time, whereas mrna capture adds approximately. hours. The entire workflow, from input RNA to sequencing-ready library, can easily be completed in a standard workday. All KAPA RNA library construction workflows are automation-friendly. 3

KAPA RNA s (green) enable highly efficient conversion of input RNA (enriched by depletion or mrna capture) to adapter-ligated library. Higher final library yields (A) are therefore achieved with fewer cycles of amplification, as compared to using the workflow from a different supplier (gray). Because fewer reads are associated with unwanted content (PCR duplicates; (B)); and residual (C), a bigger proportion of sequencing data is associated with s of interest (D). Libraries were prepared from different inputs of Universal Human Reference (UHR) RNA (Agilent Technologies), as indicted on the x-axis of each graph, using either an depletion workflow (left) or mrna capture (right) prior to library construction. The lowest input for the mrna capture workflow ( ng) is five-fold lower than the recommended minimum input for the KAPA mrna capture workflows. Paired-end (2 x bp) sequencing was performed on an Illumina HiSeq instrument. Data were sub-sampled to million reads per sample for analysis. Each bar represents the average of three technical replicates. Transcript abundance was quantified using Kallisto. 4

Libraries were generated from ng ( depletion) or ng (mrna capture) of high quality UHR RNA using the manufacturers standard recommendations for each workflow, where possible. (A) For the most highly expressed s, Roche workflows resulted in more even coverage across the entire length, as compared to the workflows from two other suppliers. This is evident both from normalized coverage plots and the coverage coefficient of variation (CV). KAPA RNA workflows, employing KAPA HiFi HotStart ReadyMix for library amplification, also better preserve difficult GC-rich regions (outlined in red), as highlighted in IGV plots of select regions of the YBX (B) and SLC2A4RG (C) genes.

KAPA RNA s with RiboErase (HMR) Globin (green) allows for the simultaneous depletion of and globin s from blood-derived RNA. Effective RNase H-based depletion and highly efficient library construction results in fewer unwanted s (A) and PCR duplicates (not shown) as compared to the workflow from a different supplier, which employs bead-based depletion (orange). This translates to more complex libraries (B) and a larger number of sequencing reads associated with s of interest (C). In addition, the Roche workflow results in much lower levels of off-target depletion (D). Libraries were prepared from different inputs of RNA extracted from human blood, as indicated on the x-axis of each graph. The ng input is lower than the recommended minimum input for the A workflow. Paired-end (2 x bp) sequencing was performed on an Illumina HiSeq instrument. Data were sub-sampled to 7 million reads per sample for analysis. Each bar represents the average of three technical replicates. Transcript abundance was quantified using Kallisto. To assess off-target depletion, abundances were aggregated at the gene level, TMM-normalized and differential expression calculated. The expression profiles of libraries generated with or without globin depletion were subsequently compared to assess off-target depletion for each workflow. 6

Top: Libraries were constructed with the KAPA RNA with RiboErase (HMR), from three different FFPE-derived RNA samples, and a fresh-frozen (FF) sample originating from the same biological specimen as the breast tumor FFPE sample. RIN and DV values are different quality scores, determined with the Agilent 2 Bioanalyzer, RNA 6 Pico and Agilent Expert software. The breast tumor FFPE sample likely contains a significant amount of crosslinked material (circled), which artificially inflated the DV value. Bottom: Libraries were prepared from ng or ng inputs of the respective samples. Paired-end (2 x bp) sequencing was performed on an Illumina HiSeq instrument. After removal of residual and duplicate reads, data were sub-sampled to 4 million reads per sample. Pearson correlation plots are shown for replicates of the same sample and input (A, B and C), different inputs of the same sample (D), and between the fresh-frozen and FFPE breast tumor samples, for both the and ng inputs (E and F). 7
