SARS-CoV-2 Monoclonal Antibodies Against Spike and Internal Proteins for Therapeutics and Diagnostics
SUMMARY
- As of February 2021, there have been over 107 million cases and over 2 million deaths caused worldwide by the novel virus SARS-CoV-2. Few vaccination and treatment approaches are currently in use with many in development.
- The inventors isolated antibodies specific to spike and internal proteins of SARS-CoV-2 from a unique cohort of COVID-19 patients. The antibodies target non-overlapping epitopes and most afford neutralization activity.
- The product is a panel of over 100 antibodies that bind various SARS-CoV-2 proteins and can be used in both therapeutic and diagnostic applications.
- Antibodies were able to neutralize virus in a live SARS-CoV-2 viral plaque assay with Vero TMPRS22 cells.
