Biofluid microRNA Sequencing is a next-generation sequencing (NGS)-based method to comprehensively detect microRNA extracted from various biofluid samples. It can profile microRNA levels and predict novel microRNAs. Our pioneered biofluid microRNA sequencing ensures the highest level of reproducibility, specificity, sensitivity and accuracy for your project.
MicroRNAs (miRNAs) are conserved, endogenous, non-coding, small (18–25 nucleotides), single-stranded molecules that regulate gene expression at a post-transcriptional level by binding to the 3' untranslated region (UTR) of mRNA. miRNAs are present in circulating blood plasma, as well as within other biofluids such as exosomes, urine, cerebral spinal fluid and even breast milk. Biofluid miRNAs represent a potential novel approach for diagnostic screening. Indeed, characteristic changes in the miRNA profiles from biofluid have identified unique signatures that could be developed as novel biomarkers for several cancers or other conditions.
We know the challenges in sequencing miRNAs from biofluid samples and overcome this by taking advantage of years of in-house experience in working with liquid biopsies. Over the years, we have conducted thousands of miRNA expression profiling experiments from biofluids such as plasma and exosomes. We combine next-generation sequencing (NGS) and specialized RNA extraction and purification kits for biofluid microRNA sequencing to provide sensitive and accurate miRNA expression profiling, contributing to the discovery and validation of novel non-invasive biomarkers for a range of diseases.

Sample storage: RNA can be dissolved in ethanol or RNA-free ultra-pure water and stored at -80°C. RNA should avoid repeated freezing and thawing.
Shipping Method: When shipping RNA samples, the RNA sample is stored in a 1.5 mL Eppendorf tube, sealed with sealing film. Shipments are generally recommended to contain 5-10 pounds of dry ice per 24 hours.
Deliverable: FastQ, BAM, coverage summary, QC report, custom bioinformatics analysis.
