Overview

Illumina Rapid mRNA Prep offers the fastest and easiest mRNA-Seq library prep solution in the Illumina portfolio. A streamlined, 30-minute one-tube reaction combines cDNA synthesis and on-bead tagmentation. The rapid workflow supports low RNA sample inputs (1–1000 ng) and delivers high-accuracy nonstranded gene expression data.

Key features

  • Fast, simplified library prep

    The entire simplified workflow, including poly(A) capture and PCR steps, requires only 3 hours to generate a sequencing-ready mRNA library.

  • Optimized performance

    Provides excellent poly(A) capture efficiency and preserves library complexity, minimizing required sequencing depth for accurate, unbiased detection of the coding transcriptome.

  • High-quality data from low-input samples

    Reproducible results from as little as 1 ng of high-quality RNA* while achieving uniform coverage. 

    *Not compatible with formalin-fixed, paraffin-embedded (FFPE) samples.

FAQ

Step 1: Capture poly(A) RNA with the Illumina mRNA Capture Kit

Step 2: Illumina Rapid RNA Prep combines cDNA synthesis and on-bead tagmentation in a single-tube, 30-min reaction

Step 3: PCR adds index adapters

Step 4: Clean up with included Illumina Purification Beads

Illumina Rapid RNA Prep is available in 96-sample and 16-sample configurations. Illumina mRNA Capture is also available in 96-sample or 16-sample configurations.

Both methods start with oligo(dT) magnetic bead capture of poly(A) mRNA. Then Illumina Rapid mRNA Prep produces nonstranded libraries using tagmentation (3 hr total workflow time and < 1.5 hr hands-on time), while Illumina Stranded mRNA Prep produces stranded libraries using ligation (6.5 hr total workflow time and < 3 hr hands-on time).
