Biofluid small RNA sequencing is a method that combines the next-generation sequencing (NGS) with optimized RNA handling and library preparation. It can improve the quality of small RNA sequencing in the biofluid and can accurately and comprehensively analyze small RNA molecules, including siRNAs, piRNAs, snoRNAs, snRNAs at one time. It is highly recommended for the analysis of small RNA variations and rare sequences.
Small RNAs, which are defined as short (>200 nucleotides, often 18 to 30 nucleotides), usually non-coding RNA molecules, consist of a diverse category of regulatory RNAs including microRNA (miRNA), small interfering RNA (siRNA), piwi-interacting RNA (piRNA), small nucleolar RNA (snoRNA), small nuclear RNA (U-RNA or snRNA), tRNA-derived small RNA, etc. Small RNA sequencing (RNA-seq) approach allows us to profile small RNA molecules, discover new forms of small RNA, detect differentially expressed RNAs and predict their possible functions. Biofluid small RNA sequencing provides credible data with professional bioinformatics analysis, which can truly reflect the abundance of transcript expression, and achieve unbiased and accurate quantification for small RNA in biofluid samples such as exosomes. Biofluid small RNA sequencing achieves high precision in base calling and quantification for small RNAs from biofluid in a specific space-time state. With optimized RNA handling and library preparation, our small biofluid RNA-seq service can facilitate studies with a variety of human biofluid samples. As circulating small RNAs are found associated with a range of human diseases, biofluid small RNA sequencing can be used to study human diseases such as cancer, myocardial injuries, hepatic diseases, and neurodegenerative diseases and identify potential biomarkers.
