Biofluid Biomarker Discovery

Unprecedented depth and throughput for your biomarker discovery in biofluids

For many studies, biofluid samples are more easily available than tissue samples. Our Biofluid Biomarker Discovery service enables deep and reproducible quantification of biofluid proteomes. It allows the identification of the most promising, actionable biomarkers to support clinical decision making.

    Biofluids are known to have a high dynamic range compared to tissue, requiring a highly robust technology for proteomic analysis. The Biofluid Biomarker Discovery service is based on Biognosys’ proprietary Hyper Reaction Monitoring (HRM™) technology,  enabling the quantification of biofluid proteomes with great specificity and depth.

    Depending on the sample type, the application offers a depth of up to 5,000 proteins to identify differentially regulated proteins as biomarker candidates in an unbiased, hypothesis-free manner. We also provide highly multiplexed targeted proteomics with absolute quantification for customized panels of proteins.

    In blood, we offer a choice of standard, non-depleted plasma/serum profiling or depleted plasma/serum profiling.

    Our biofluid-based profiling workflows can be combined with our proprietary PQ500 plasma panel. PQ500 is a reference panel for absolute quantification, developed based on our expertise in targeted proteomics.

    Biofluid Biomarker Discovery is scalable to thousands of samples at industry-leading throughput.


    The results are presented and discussed with you in a dedicated conference call and delivered electronically in PDF and Excel formats.
