ScriptSeq™ mRNA-Seq Library Preperation Kit (Illumina-compatible)


ScriptSeq™ mRNA-Seq Library Preperation Kit (Illumina-compatible)

24 Rxns

The ScriptSeq™ mRNA-Seq Library Preparation Kit (Illumina-compatible)* uses a unique terminal-tagging technology* that simplifies the preparation of directional, paired-end libraries from rRNA-depleted or poly(A)-enriched RNA (Fig. 1). The kit is suitable for any animal, plant, or bacterial species, and enables library preparation in about 3 hours.

The ScriptSeq™ mRNA-Seq Library Preparation Kit (Illumina-compatible):

  • Enables strand-specific adaptor-tagging for directional paired-end sequencing using standard Illumina® sequencing primers.
  • Produces cluster-ready libraries in about 3 hours without the need for end-repair, adaptor ligations, shearing of the cDNA, or gel electrophoresis.
  • Uses random-primed cDNA synthesis to enable library preps from rRNA-depleted RNA or Poly(A)+ RNA from any animal, bacteria, or plant species.
  • Is barcode-capable for Illumina-compatible barcodes (available separately) or user-defined barcodes.
  • Produces mRNA-Seq libraries that demonstrate high concordance with MAQC qPCR data (Fig. 3).
  • Requires as little as 50 ng of rRNA-depleted RNA.
  • Generates highly mappable libraries from intact, partially degraded, and FFPE RNA samples (Table 2).

Table 2. The ScriptSeq™ mRNA-Seq Kits generate high quality libraries from rRNA-depleted RNA, poly(A) RNA, and FFPE RNA samples. The specified RNAs were treated with EPICENTRE's Ribo-Zero™ rRNA Removal Kit (Human/Mouse/Rat) or a commercial poly(A) RNA enrichment kit. ScriptSeq (Illumina-compatible) libraries were prepared and sequenced on an Illumina® GAII sequencer. UHRR, Universal Human Reference RNA; BrRR, Brain Reference RNA.
