TY - GEN A1 - Döring, Sarah T1 - Vergleichende Darstellung SARS-CoV-2-spezifischer Nanobodys aus unterschiedlichen Wirtsorganismen N2 - Aufgrund der anhaltenden COVID-19-Pandemie werden neutralisierende Therapeutika benötigt. Eine Möglichkeit zur Behandlung stellt die Verwendung monoklonaler Anti-SARS-CoV-2-Immun-globuline dar. Ihre Produktion in Säugetierzellen ist jedoch schwer skalierbar, um den weltweiten Bedarf zu decken. VHH-Antikörper, auch Nanobodys genannt, bieten hierfür eine Alternative, da sie eine hohe Temperaturstabilität aufweisen und eine kostengünstige Produktion in prokaryotischen Wirtsorganismen ermöglichen.

Furthermore ICP-MS offers a very high multi-element coverage so that many elements of the periodic table can be detected simultaneously. In this series of lectures, we want to focus on the historical developments, fundamentals, instrumentation and novel applications of ICP-MS in the life and material sciences.

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.
