Unlocking the Small RNA Universe: New Paradigms in MicroRNA Extraction

The exploration of the small RNA universe, including microRNAs (miRNAs), circular RNAs (circRNAs), and long non-coding RNAs (lncRNAs), is at the forefront of modern research in immuno-oncology, liquid biopsy development, and disease mechanism elucidation. Despite their critical biological relevance, the accurate analysis of these RNA species remains challenging. In particular, the performance of downstream applications such as Small RNA-Seq is frequently constrained by the intrinsic limitations of conventional silica-based extraction methods, which often fail to efficiently recover small, fragmented, or ultra-low abundance transcripts.

This presentation introduces a next-generation paradigm in RNA isolation based on Silicon Carbide (SiC) technology. Unlike traditional extraction approaches, SiC resin exhibits a high and uniform affinity for all RNA species, independent of molecular size or GC content. This enables comprehensive RNA recovery without the use of hazardous phenol reagents or the addition of carrier RNA, streamlining workflows while improving data quality.

SiC-based extraction is particularly advantageous for challenging sample types, including low-input, degraded, and biofluid-derived specimens.

Performance data demonstrate that SiC technology delivers a marked increase in genome-mapped reads and significantly improved small RNA mapping efficiency compared to conventional methods. By minimizing background noise and reducing wasted sequencing reads, this approach not only enhances sensitivity for rare RNA biomarker discovery but also substantially optimizes sequencing cost efficiency.
