Choose the right tool for the job

Are you leveraging the appropriate technology for your research? The scientific community is now widely acknowledging that there are specific applications best served by arrays and others by RNA sequencing (RNA-Seq). Additionally, many see opportunities to harness the power of both technologies for expression studies.

Look beyond the gene

Expand your biomarker discovery universe

Due to the complexity of the transcriptome, scientists are now aware of the importance of expanding their scope beyond the gene level. Gaining attention as critical regulators of coding RNA and alternative splicing, lncRNA have been implicated in a wide range of diseases, opening up the possibility of their use as biomarkers and therapeutic targets.8 In addition, because an estimated 95% of human genes undergo alternative splicing,9,10 and the disruption of such events is known to be highly associated with many diseases,9 alternatively spliced variants are also promising candidates for biomarkers.11

A growing body of evidence has shown that identifying lncRNA and alternative splicing events can be very challenging with RNA-Seq.

  • To reveal low-abundance transcripts and splice junctions, very deep sequencing is required— which is not cost effective.12
  • Detection of alternative splicing events with RNA-Seq is challenging due to sampling noise, requiring >300 million reads providing only 80% confidence.1,3
  • Due to significant biases introduced in library preparation, interpreting exon-level RNA-Seq results—especially when looking for alternative splicing events—should be done with caution.13

Simple workflow. Fast analysis. Cost effective.

Human, mouse, and rat assays from Applied Biosystems allow researchers to:

  • Generate comprehensive datasets quickly across known pathways and genes, allowing time-consuming RNA-Seq experiments to be focused on discovery of unknown transcripts
  • Perform global gene expression profiling with as little as 100 pg of RNA or 500 pg of degraded formalin-fixed, paraffin-embedded (FFPE) RNA— sample inputs which are not easily amenable to RNA-Seq
  • Better quantify low-abundance transcripts7
  • Validate complex RNA-Seq data quickly and easily
  • Quickly and cost-effectively complete high-volume studies7
  • Analyze data in minutes with free Transcriptome Analysis Console (TAC) software

Improve turnaround time. Data to insight in minutes.
With simple and free TAC software you can:
  • Identify genes, exons, and alternative splicing events
  • Explore expression changes across networks of miRNA and target genes
  • Visualize gene models with exon and junction signals
