Small noncoding RNAs act in gene silencing and post-transcriptional regulation of gene expression. Small RNA sequencing (RNA-Seq) is a technique to isolate and sequence small RNA species, such as microRNAs (miRNAs). Small RNA-Seq can query thousands of small RNA and miRNA sequences with unprecedented sensitivity and dynamic range.
With small RNA-Seq you can discover novel miRNAs and other small noncoding RNAs, and examine the differential expression of all small RNAs in any sample. You can characterize variations such as isomiRs with single-base resolution, as well as analyze any small RNA or miRNA without prior sequence or secondary structure information.
Generate miRNA sequencing libraries directly from total RNA to understand the role of noncoding RNA.
Illumina offers a broad portfolio of epigenetic analysis tools for investigators interested in studying epigenetic modifications and small RNA gene regulation.
