Before starting DNA-Free RNA Treat the RNA sample with DNase I to remove all traces of DNA. Then, remove the DNase I prior to the TotalScript cDNA synthesis procedure. RNA Quality For best results, use intact, non-fragmented RNA samples with RIN >7 as assayed using a Bioanalyzer. Amount of RNA TotalScript is optimized for 1-5 ng of total RNA input, without any prior ribosomal RNA removal or poly(A) enrichment. It is crucial to carefully quantify total RNA prior to beginning. For optimal results, do not exceed the maximum amount of RNA (5 ng). cDNA Primer and Buffer Combination The choice of 1st strand cDNA primer and 1st strand cDNA Buffer to use in the 1st strand cDNA synthesis procedure (step 3) and the attributes of the resulting TotalScript library are dependent on the RNA sample. a) When using Total RNA sample: Follow the procedure in Part 3.A. For best results use the TotalScript Optimized Buffer. Then, use these guidelines for the choice of cDNA primer that best meets your needs. • Oligo (dT) Primer yields 3′-bias libraries with <5% rRNA reads • Random Hexamer Primers yields even transcript coverage with <40% rRNA reads • Mixed Primer (Oligo (dT) Primer + 1:3 dilution of Random Hexamer Primers) yields slight 3′-bias libraries with <25% rRNA reads See Fig. 1 for TotalScript libraries produced from total RNA samples using each of these primer options.

Total RNA Samples For best results use the TotalScript Optimized Buffer for total RNA samples. Use the following guidelines for the choice of cDNA primer that best meets your needs. • Oligo (dT) Primer yields 3′-bias libraries with <5% rRNA reads. • Random Hexamer Primers yields libraries with even transcript coverage and <40% rRNA reads. • Mixed Primer (Oligo (dT) Primer + 1:3 dilution of Random Hexamer Primer) yields libraries with slight 3′-bias and <25% rRNA reads. Figure 1. TotalScript RNA-Seq libraries were made from 5 ng of total UHR RNA (Universal Human Reference RNA) using the Random Primer, Mixed Primer or Oligo(dT) Primer cDNA synthesis strategies (step 3.A) and the TotalScript Optimized Buffer. The amount of rRNA contamination in the resulting TotalScript libraries will differ considerably based on the cDNA priming approach. Random Hexamer Primer produces <40% of reads mapping to rRNA, Mixed Primer produced <25% rRNA mapped reads and Oligo(dT) Primer produced <5% rRNA reads. The samples produced by Oligo(dT) Primer also result in stronger 3′-bias read distribution. Different sources of RNA may not necessarily produce the same level of rRNA contamination. 4 www.epicentre.com TotalScript™ RNA-Seq Kit Important! If using the Mixed Primer option, dilute the Random Hexamer Primer 1:3 with nuclease free water. Note: It is recommended to use the Control RNA as a positive control for library prep.

Sequencing TotalScript RNA-Seq libraries If sequencing TotalScript libraries with HiSeq, HiScanSQ, or GAIIx, the TruSeq Dual Index Sequencing Primer Box must be used: • TruSeq Dual Index Sequencing Primer Kit, Single Read, Cat. No. FC-121-1003, OR • TruSeq Dual Index Sequencing Primer Kit, Paired End, Cat. No. PE-121-1003 TruSeq Dual Index Sequencing primers will be used in place of HP6, HP7, and HP8 primer mixes. Alternatively, if TruSeq Dual Index Sequencing Primer Box is not accessible, sequencing primers provided in the TotalScript kit can be used. TotalScript™ Read 1, Read 2, and Index Sequencing Primers are provided as 200X (100 um). Dilute TotalScript Read 1 Sequencing Primer into HP6. Dilute TotalScript Read 2 Sequencing Primer into HP7. Dilute TotalScript Index Read Sequencing Primer into HP8. TotalScript libraries are compatible with the MiSeq system, and do not require the included sequencing primers or the TruSeq Dual Index Sequencing Primer Boxes for sequencing on a MiSeq. Note: The sequence generated by the Read 1 sequencing primer corresponds to the reverse complement (antisense) sequence of the original RNA molecule.
