Obtaining a high titer of polyclonal antibodies from rats to the SARS-CoV-2 nucleocapsid protein and its N- and C-terminal domains for diagnostic test development
J Immunol Methods. 2023 Sep 11:113558. doi: 10.1016/j.jim.2023.113558. Online ahead of print.ABSTRACTSevere Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is an enveloped, plus-stranded RNA virus responsible for the Coronavirus Disease 2019 (COVID-19). Patients infected with COVID-19 may be asymptomatic or have symptoms ranging from mild manifestations to severe cases of the disease that could lead to death. The SARS-CoV-2 genome encodes 4 structural proteins, including the Spike protein (S), the Nucleocapsid protein (N), membrane protein (M) and, the envelope (E). The N protein forms a major component of the ribonu...

Broadening a SARS-CoV-1-neutralizing antibody for potent SARS-CoV-2 neutralization through directed evolution
Sci Signal. 2023 Aug 15;16(798):eabk3516. doi: 10.1126/scisignal.abk3516. Epub 2023 Aug 15.ABSTRACTThe emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) underscores the need for strategies to rapidly develop neutralizing monoclonal antibodies that can function as prophylactic and therapeutic agents and to help guide vaccine design. Here, we demonstrate that engineering approaches can be used to refocus an existing antibody that neutralizes one virus but not a related virus. Through a rapid affinity maturation strategy, we engineered CR3022, a SARS-CoV-1-neutralizing antibody, to bind to the receptor...

Subcutaneous and intramuscular administration of a SARS-CoV-2 vaccine are similarly effective in generating a humoral response in domestic goats (Capra hircus)
Am J Vet Res. 2023 Aug 14:1-6. doi: 10.2460/ajvr.23.05.0117. Online ahead of print.ABSTRACTOBJECTIVE: To determine severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) serum antibody titers in domestic goats after SC and IM administration of an experimental, veterinary SARS-CoV-2 vaccine.ANIMALS: 31 healthy adult domestic goats from 4 zoological institutions.METHODS: On day 0, blood was collected for baseline serum titer before vaccination with 1 mL SARS-CoV-2 recombinant S protein vaccine SC (n = 22) or IM (n = 9). A booster vaccination was administered 21 (SC group) or 28 days (IM group) after the initial vaccine...
