The product previously known as the TruSeq Stranded mRNA Library Prep Kit (Cat. No. RS-122-2101, RS-122-2102, and RS-122-2103) is now called TruSeq Stranded mRNA. The product configuration has changed. In the new configuration, the library preparation and index adapters can be purchased separately. The list of components available for individual purchase can be found in the “Select Product(s)” section.

Product Highlights

TruSeq Stranded mRNA offers a streamlined, cost-efficient, and scalable solution for coding transcriptome analysis. It is compatible with a wide range of samples.

Strand Orientation Detection

Get precise measurement of mRNA strand orientation for detection of antisense transcription, enhanced transcript annotation, and increased alignment efficiency. High coverage uniformity enhances the discovery of features such as alternative transcripts, gene fusions, and allele-specific expression.


Stranded information identifies from which of the 2 DNA strands a given RNA transcript was derived. This information provides increased confidence in transcript annotation, particularly for nonhuman samples. Identifying strand origin increases the percentage of reads that align, reducing sequencing costs per sample.


The workflow enables robust interrogation of both standard and low-quality samples, and workflows compatible with a wide range of study designs.
