• Towards a better understanding of cancer and personalized medicine

    Cancer remains one of the major causes of death and continues to require massive global research efforts. The ability to discover and validate more cancer-related protein biomarkers will be instrumental in addressing this huge healthcare challenge – paving the way for better understanding, diagnosis, and personalized treatment for cancer patients. 

    Our Oncology II panel is a high-throughput, multiplex immunoassay enabling analysis of 92 inflammation-related protein biomarkers across 96 samples simultaneously. This high level of multiplexing is achieved without any compromise on data quality, thanks to our proprietary Proximity Extension Assay (PEA) technology

    The panel comprises 92 putative cancer-related human proteins that participate in biological mechanisms that are central to the initiation and progression of cancer, e.g. angiogenesis, cell-cell signaling, cell-cycle control, and inflammation. For optimal assay performance, each analyte in the panel has been assessed in terms of sample material, specificity, precision, sensitivity, dynamic range, matrix effects and interference. Replacing our previous oncology panel (Proseek Multiplex Oncology I v2 96×96), this panel provides 60 completely new, high quality cancer-related biomarker assays, reducing overlap with other Proseek Multiplex panels and futher improving overall assay performance.

    An overview of how the 92 biomarker assays in the panel are classified according to Biological Process, Disease Area, Tissue Expression and Protein Class (based on widely used public-access bioinformatic databases, including Uniprot, Human Protein Atlas, Gene Ontology (GO) and DisGeNET) can be seen in the charts below. These charts are interactive: click on a chart-bar or pie-segment to see the list of biomarkers in that classification. Each item in the list links to the detailed biomarker page with validation data.

    For optimal assay performance, each immunoassay in the panel has been assessed in terms of specificity, precision, sensitivity, dynamic range, matrix effects and interference in biological material.

    A comprehensive list of all protein biomarkers that can be measured using the currently available Proseek Multiplex panels can be seen on the biomarker library page.

    If you prefer not to run the assay yourself, let our experts here at Olink do this for you via our Analysis Service.

    The biomarker pages linked to below include calibrator curves that show the performance of each assay with the estimated sensitivity and dynamic range parameters indicated. These curves are generated during the assay validation process using recombinant antigens, with data presented as Normalized Protein eXpression (NPX) values plotted against protein concentration (in pg/mL). Please note that when analyzing biological samples the data generated will be given in the form of relative quantification (NPX values) and cannot be converted to absolute protein concentrations. For more info about NPX measurements, please view the FAQ.
