Sotrovimab
Based on 5 publication(s) in Google Scholar
Sotrovimab (VIR 7831) is a human IgG1κ pan-sarbecovirus monoclonal antibody (mAb), neutralizes SARS-CoV-2, SARS-CoV-1, and multiple other sarbecoviruses. Sotrovimab is developed based on S309, exhibits a long half-life and great bioavailability in the respiratory mucosa. Sotrovimab could result in immune-mediated viral clearance and prevent progression of Covid-19 early in the course of disease.

Sotrovimab neutralizes both SARS-CoV-2 and SARS-CoV, but does not directly block virus receptor binding[2].
Sotrovimab (100 μg/mL, injected for 200 s, v=30 μL/min) binds efficiently to surface-expressed SARS-CoV-2 S[3].
Sotrovimab (0.3 ng/mL-20 mg/mL; 30 min) neutralizes SARS-CoV-2 pseudo-typed virus in vitro, and also against the Alpha, Beta, Gamma, Delta and Kappa variant viruses with IC50s of 187.2 ng/mL, 71.9 ng/mL, 73.11 ng/mL, 51.3 ng/mL, and 118.64 ng/mL, respectively[3].

Immobilized SARS-CoV-2/2019-nCoV Spike Protein (RBD, His Tag) can bind Sotrovimab. The EC50 for this effect is 1.47 ng/mL. -
Loaded Sotrovimab on AHC2 biosensor, can bind SARS-CoV-2 S1 Protein (Omicron, B.1.1.529, His, HY-P74445) with an affinity constant of 1.168E-08 M as determined in BLI assay.
