Biofluids

Cell-free biofluids such as blood plasma, cerebrospinal fluid (CSF), bile, and saliva contain RNA molecules that have either been secreted by cells in local tissue or transferred from other parts of the body by blood or lymph.


These RNA molecules are emerging as potential biomarkers for a wide range of diseases, as changes in the RNA profile of various biofluids may offer key information for diagnosis, tracking disease progression, and monitoring treatment response. 


RNA sequencing is a powerful tool for screening potential RNA biomarkers in biofluids. 

Research applications

Early Diagnostics

Early Diagnostics

Quantification of  RNA biomarkers to enable diagnosis at earlier stages and potentially mitigate or delay disease progression

Companion diagnostics

Companion Diagnostics

Tracking central biomarkers along disease progression to monitor and provide optimal treatment for individual patients

Treatment response validation

Treatment response validation

Monitoring RNA biomarker levels to evaluate treatment performance

RNA biomarkers offer several advantages over their protein counterparts:

    Biofluid sequencing with omiics

    Cell-free biofluids have ultra-low RNA content. The power of sequencing RNA in biofluids for biomarker screening therefore relies heavily on expert sample preparation and bioinformatics to ensure the highest quality RNA samples and results.


    Omiics specializes in ultra-low input samples for RNA NGS, having ample experience with biofluids including plasma, CSF, saliva, bile, etc.

    We use optimized protocols for biofluid samples, performed under highly controlled and traceable conditions in our Aarhus-based laboratory. With our meticulous laboratory work, and expert bioinformatic analysis, we can assure high quality and reliable results.



    Sample preparation


    • RNA extraction for multiple types of biofluids
    • Initial step of extracellular vesicle (EV) isolation (optional)
    • Library preparation using optimized protocols for low RNA input samples


    Sequencing


    • Illumina based small RNA (SE75) or total RNA (PE100, PE150) sequencing
    • Small RNA - miRNA, tRNA, tsRNA, piRNA, etc.
    • Total RNA - mRNA, lncRNA, circRNA


    Data analysis


    • Vast in-house experience with state-of-the-art bioinformatic approaches
    • Standard or custom-made analysis
    • Support on interpretation and suggestions for follow-up experiments
