A streamlined, aptamer-based multiplex proteomic assay for diagnostic applications

To enable the application of protein signatures identified in our highly multiplexed biomarker discovery platform to real-world diagnostics, we developed a streamlined, plate-based assay that employs the same principles as the larger SOMAScan assay. The plate-based assay is sensitive (sub-picomolar), robust, rapid, automatable, and can multiplex upwards of 60 analytes. We have used this platform to seamlessly translate sets of biomarkers identified in our SOMAScan assay to a practical non-small cell lung cancer diagnostic.
