Total RNA Sequencing

Introduction to Total RNA Sequencing

Whole-transcriptome analysis with total RNA sequencing (RNA-Seq) detects coding plus multiple forms of noncoding RNA. Total RNA-Seq can accurately measure gene and transcript abundance, and identify known and novel features of the transcriptome.

Total RNA-Seq provides optimal coverage in normal or low-quality samples. Species-specific ribosomal RNA probes can efficiently remove abundant RNA species. This leaves both fragmented and intact transcripts of interest for library capture.

Advantages of Total RNA Sequencing

Advantages of Total RNA Sequencing

Total RNA-Seq analyzes both coding and multiple forms of noncoding RNA for a comprehensive view of the transcriptome.

  • Captures both known and novel features
  • Allows researchers to identify biomarkers across the broadest range of transcripts
  • Enables a more comprehensive understanding of phenotypes of interest
  • Allows profiling of the whole transcriptome across a wide dynamic range

Transitioning from Whole-Genome Arrays to Total RNA-Seq

Dr. Avrum Spira, a pulmonary and critical care physician at Boston University Medical Center, started a lab with the goal of analyzing samples with whole-genome gene expression arrays, to study potential biomarkers for pulmonary disorders. Learn how Spira’s lab uses total RNA-Seq to uncover novel and rare transcripts that may not be detectable on expression arrays.

Total RNA Sequencing Workflow

Illumina sequencing by synthesis (SBS) chemistry is the most widely adopted next-generation sequencing (NGS) technology, producing approximately 90% of global sequencing data.*

In addition to high-quality data, Illumina offers integrated whole-transcriptome sequencing workflows that simplify the entire process, from library preparation to data analysis and biological interpretation.

RNA Sequencing Considerations

Each RNA-Seq experiment type—whether it’s gene expression profiling, targeted RNA expression, or small RNA analysis—has unique requirements for read length and depth. This bulletin reviews experimental considerations and offers resources to help with study design.
