Description:

New catalog number RVV00305

VHH-72 is a single-domain, heavy chain-only antibody or nanobody isolated from a llama immunized with spike from SARS-CoV-1, which is cross-reactive against spike from SARS-CoV-2. The Llama VHH was engineered into a bivalent form by fusion to hIgG1 Fc for a humanized SARS-CoV-1– and SARS-CoV-2–neutralizing capacity. VHH-72 binds to an epitope in the receptor binding domain (RBD) of the spike protein that is highly conserved in members of the Sarbecovirus subgenus of the betacoronaviruses, prevents the interaction of the SARS-CoV-1 and SARS-CoV-2 RBD with angiotensin converting enzyme 2 (ACE2), and presumably destabilizes the spike protein. Recombinant Human anti-SARS-CoV-2 Spike Protein Receptor Binding Domain, Clone VHH-72, is expressed in XtenCHO.antibody therapies and diagnostic antigen-based tests.
