This Core provides turnkey services to Clinical and Basic Science Investigators (clients) concluding in the laboratory measurement of biomarkers (cytokines and other proteins) using specialized immunochemistry techniques. The Core can also provide clients (either within UNC or around the world) with cost projections (as needed for preparing grant descriptions for methods and resources related to Core services), study design consulting, and will provide barcode labels and sample storage tubes for the collection and archival cryostorage of biological samples. Routine levels of such services are included in the published rates for ELISA and Multiplex biomarker analysis. Unusually intensive requests for assistance will be provided at the published hourly consulting rate.
