The rapid evolution of the virus requires adaptation of diagnostic and therapeutic applications. Objectives: In this study, we describe camelid heavy-chain-only antibodies (hcAb) as useful tools for novel in vitro diagnostic assays and for therapeutic applications due to their neutralizing capacity. Methods: Five antibody candidates were selected out of a na{\"i}ve camelid library by phage display and expressed as full length IgG2 antibodies. The antibodies were characterized by Western blot, enzyme-linked immunosorbent assays, surface plasmon resonance with regard to their specificity to the recombinant SARS-CoV-2 Spike protein and to SARS-CoV-2 virus-like particles. Neutralization assays were performed with authentic SARS-CoV-2 and pseudotyped viruses (wildtype and Omicron). Results: All antibodies efficiently detect recombinant SARS-CoV-2 Spike protein and SARS-CoV-2 virus-like particles in different ELISA setups. The best combination was shown with hcAb B10 as catcher antibody and HRP-conjugated hcAb A7.2 as the detection antibody. Further, four out of five antibodies potently neutralized authentic wildtype SARS-CoV-2 and particles pseudotyped with the SARS-CoV-2 Spike proteins of the wildtype and Omicron variant, sublineage BA.1 at concentrations between 0.1 and 0.35 ng/mL (ND50). Conclusion: Collectively, we report novel camelid hcAbs suitable for diagnostics and potential therapy.}, language = {en} } @misc{SchloerHirschbergBenAmoretal.2022, author = {Schl{\"o}r, Anja and Hirschberg, Stefan and Ben Amor, Ghada and Meister, Toni Luise and Arora, Prerna and P{\"o}hlmann, Stefan and Hoffmann, Markus and Pf{\"a}nder, Stephanie and Eddin, Omar Kamal and Kamhieh-Milz, Julian and Hanack, Katja}, title = {SARS-CoV-2 neutralizing camelid heavy-chain-only antibodies as powerful tools for diagnostic and therapeutic applications}, series = {Zweitver{\"o}ffentlichungen der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, journal = {Zweitver{\"o}ffentlichungen der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, number = {1280}, issn = {1866-8372}, doi = {10.25932/publishup-57012}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-570124}, pages = {14}, year = {2022}, abstract = {Introduction: The ongoing COVID-19 pandemic situation caused by SARS-CoV-2 and variants of concern such as B.1.617.2 (Delta) and recently, B.1.1.529 (Omicron) is posing multiple challenges to humanity.
