mRNA sequencing (mRNA-Seq) has rapidly become the method of choice for analyzing the transcriptomes of disease states, of biological processes, and across a wide range of study designs. In addition to being a highly sensitive and accurate means of quantifying gene expression, mRNA-Seq can identify both known and novel transcript isoforms, gene fusions, and other features as well as allele-specific expression. mRNA-Seq delivers a complete view of the coding transcriptome that is not restricted by the filter of prior knowledge.
mRNA-Seq provides a number of advantages over gene expression arrays in analyzing the transcriptome.
Ratio compression is an established technical limitation of gene expression arrays that reduces dynamic range and can mask or alter measured transcriptional changes.1–3 In contrast, mRNA-Seq is not subject to this bias and provides more comprehensive and accurate measurements of gene expression changes.
Additionally, mRNA-Seq can provide strand information, which enables the detection of antisense expression, allows more accurate quantification of overlapping transcripts, and increases the percentage of alignable reads.
Streamlined, cost-efficient, and scalable library preparation for mRNA-Seq.
Desktop sequencer supporting multiple applications, enabling 5-16 mRNA samples to be sequenced in a single run.
Illumina sequencing by synthesis (SBS) chemistry is the most widely adopted NGS technology, producing approximately 90% of global sequencing data.*
In addition to our industry-leading data quality, Illumina offers integrated mRNA-Seq workflows that simplify the entire process, from library preparation to data analysis and biological interpretation.
