Abstract: Methods of detecting SARS-CoV-2 antibodies with improved specificity are described. The methods can include contacting a sample potentially containing SARS-CoV-2 antibodies with a reagent to remove non-anti-SARS-CoV-2 antibodies, such as a reagent comprising an epitope from a nucleocapsid protein or spike protein of a common coronavirus. The methods can include contacting the sample with a mutant SARS-CoV-2 nucleocapsid protein or spike protein comprising a reduced number of common coronavirus epitopes. The methods can involve comparing results from an immunoassay performed with a SARS-CoV-2 protein to results obtained from immunoassays performed with analogous protein from one or more common coronaviruses.

Abstract: The invention provides a compound comprising one, two, three or more non-natural HRC sequence of a viral spike peptide conjugated to a hydrophobic moiety via an optional linker. The hydrophobic moiety can be a membrane integrating ligand, such as a cholesterol, a sphingolipid, a glycolipid, a glycerophospholipid. The non-natural viral spike peptide is preferably a coronavirus spike protein characterized by one or more D-amino acids. The peptides of the invention inhibit viral fusion. The invention includes compositions for the delivery of compounds of the invention, such as pulmonary or nasal delivery. The invention also provides a method of treating or preventing a viral infection, including for example a SARS-CoV-2 (COVID-19) infection, in a subject in need thereof comprising administering an effective amount of a compound of the invention.
Abstract: The present invention relates to a binding molecule that binds to SARS-coronavirus-2 (SARS-CoV-2). More particularly, the binding molecule of the present invention has strong ability to bind to a spike protein (S protein) on the surface of SARS-coronavirus-2 and high neutralizing activity against SARS-coronavirus-2 and is thus very useful in the diagnosis, prevention or treatment of SARS-coronavirus infection (COVID-19).
