Hieff NGS™ MaxUp Human rRNA Depletion Kit (rRNA & ITS/ETS)



Hieff NGS MaxUp Human rRNA Depletion Kit (rRNA & ITS/ETS) is designed to remove rRNA and 45S ITS/ETS from human, mouse and rat total RNA based on RNase H-based workflow and to retain mRNA and other non-coding RNA. This kit is suitable for both intact and partially degraded RNA samples (e.g., FFPE RNA). Since degraded FFPE samples usually contain a higher proportion of ITS/ETS than fresh tissue samples, this kit adds probes in the Human 45S ITS/ETS region, and ITS removal can significantly increase the proportion of valid data in raw data.


  • Strong specificity: specifically remove rRNA and ITS/ETS from human samples, especially for FFPE samples
  • High compatibility of template starting amount: applicable to 100 ng~1μg sample
  • High removal effect: for rRNA, ITS and ETS in human\mouse and rat samples, the removal effect is more than 95%
  • Stable quality: strict batch performance and stability quality control


  • Gene Expression Research
  • Alternative splicing analysis
  • Detection and discovery of non coding RNA
  • dentification of selective polyadenylation sites
  • Fusion gene detection

  • rRNA removal specificity

For conventional samples, rRNA and ITS/EST can be removed by more than 98%, while for FFPE samples with integrity of about 50%, rRNA and ITS/EST can be removed by more than 95%. At the same time, FFPE with poor integrity can also be removed effectively.

Note: Different human RNA samples were used to remove rRNA or rRNA and ITS/ETS, and to construct libraries with RNA library Prep kit after ITS/ETS. The proportions of rRNA and ITS/ETS in offline data were analyzed by sequencing.
