Focused sequencing of specific transcripts of interest

Gene expression and fusion detection in RNA samples

Targeted RNA Sequencing

Targeted RNA-sequencing (RNA-Seq) is a highly accurate method for selecting and sequencing specific transcripts of interest. It offers both quantitative and qualitative information. Targeted RNA-Seq can be achieved via either enrichment or amplicon-based approaches, both of which enable gene expression analysis in a focused set of genes of interest. Enrichment assays also provide the ability to detect both known and novel gene fusion partners in many sample types, including formalin-fixed paraffin-embedded (FFPE) tissue.

RNA enrichment provides quantitative expression information as well as the detection of small variants and gene fusions. RNA enrichment offers the following features:

  • Compatible with difficult samples such as FFPE tissue
  • Low input (requires 10 ng of total RNA or 20 – 100 ng of FFPE RNA)
  • Detects both known and novel fusion gene partners
  • Profiles gene expression with a broad dynamic range
Advantages of Targeted Enrichment RNA Sequencing

RNA expression panels can be designed to focus on RNA sequences of interest, or custom content can be added to fully optimized and experimentally validated panels.

  • Offers a highly accurate and specific method for measuring transcripts of interest
  • Provides qualitative and quantitative information for differential expression analysis, allele-specific expression measurement, and gene fusion verification
  • Measures dozens to thousands of targets simultaneously
  • Is compatible with low-quality or FFPE-derived RNA samples

Dr. Frank Middleton from SUNY Upstate Medical University (UMU) developed a focused gene panel to screen for expression alterations caused by a newly discovered CNV in schizophrenia. See why Dr. Middleton used targeted RNA-Seq rather than PCR or arrays to analyze several hundred genes associated with schizophrenia, bipolar disorder, and autism.
