Introduction to small RNA sequencing

Since the discovery of microRNA (short ~22mer RNA sequences that bind to mRNA and inhibit translation), the study of gene expression regulation has expanded tremendously. With the advent of next-generation sequencing (NGS) in the last decade, researchers have harnessed the power of deep sequencing to further reveal the complexity of these small RNA species, which have expanded to include multiple classes of small RNA such as microRNA (miRNA), short-interfering RNA (siRNA), and piwi-interacting RNA (piRNA), among others.

Ambion RNA kits offer a perfect way to isolate and purify your samples, enabling high-quality capture of small RNA species. Leveraging the knowledge leadership of Thermo Fisher Scientific and integrating kits that isolate and purify small RNA species creates a complete solution that is optimized for small RNA analysis on the Ion S5 and Ion PGM systems. The scalability of these systems enables you to include a range of samples per run, giving you the throughput flexibility to match your experiment sizes. Although other NGS platforms can also analyze small RNA, their ultrahigh-throughput format requires batching hundreds of samples per run, potentially delaying your time to results.

Choose the Ion PGM System, which enables fast and accurate results for small RNA and targeted RNA studies, while the Ion S5 System offers higher throughput, enabling you to scale from small RNA to whole transcriptome analysis. Both systems surpass microarrays as a tool for expression analysis, with these advantages:

  • Superior sensitivity, with a greater dynamic range, to detect more transcripts and subtle changes in gene expression
  • Discrimination between sequences from closely related small RNA families
  • Detection of novel small RNA sequences
  • Digital output enabling results to be compared over time and between studies and labs
  • Close correlation with TaqMan™ Assay results
