T1 - Immunoprecipitation with Nanodiamonds for the Enrichment of Ceruloplasmin from Human Serum N2 - In this study, we developed a new immunoprecipitation method based on protein-coated nanodiamonds. Performing SDS-PAGE and using the SDS-PAGE buffer as an eluent showed that CER could be successfully enriched from human serum. Based on the copper determination with ICP-MS, the amount of bound CER on the nanodiamonds can be calculated. We could show the fulfilled mass balance of bound CER and CER in the supernatant after incubation with a known amount of CER. For isotope ratio analysis this method can be applied to compare ratios of the total copper content in human serum to copper ratios from CER enrichment.
