LC Sciences provides a fast, one-stop degradome sequencing solution – from your sample through data analysis.

Degradome sequencing (Degradome-Seq), also referred to as parallel analysis of RNA ends (PARE), a modified 5′-rapid amplification of cDNA ends (RACE) with high-throughput next-gen sequencing method. Degradome sequencing provides a comprehensive means of analyzing patterns of RNA degradation.

Degradome sequencing has been use to identify microRNA (miRNA) cleavage sites, because miRNAs can cause endonucleolytic cleavage of mRNA by extensive and often perfect complementarity to mRNAs. Degradome sequencing has revealed many known and novel plant miRNA (siRNA) targets.

  1. In plants, microRNAs tend to cause cleavage of their targets at the position between nucleotides 10 and 11 of the microRNA
  2. Next-Gen sequencing of the 5’ ends of RNA degradation products allows identification of over-represented 5’  ends (microRNA cleavage sites)
  3. Matching cleavage sites to known microRNA sequences links microRNAs to their targets
