Recombinant antigens and lentivirus for emerging SARS-CoV-2 variants

AMSBIO has announced new additions to its portfolio of tools for COVID-19 research - two monoclonal antibodies that recognize the Spike RBD (B.1.1.529, Omicron Variant) protein and neutralizes its interaction with ACE2. The human ACE2 receptor is found on the surface of type I and II pneumocytes, endothelial cells, and ciliated bronchial epithelial cells. Research has shown that ACE2 mediates COVID-19 infection through direct binding of the SARS-CoV-2 Spike protein.
 
AMSBIO’s new Spike neutralizing monoclonal antibodies (clone G10xA5 and G10xA1) recognize the SARS-CoV-2 Spike RBD (B.1.1.529, Omicron Variant) protein and neutralize its interaction with ACE2. Both these neutralizing antibodies have been functionally tested using the Spike S1 RBD (B.1.1.529, Omicron Variant) (SARS-CoV-2): ACE2 Inhibitor Screening Colorimetric Assay Kit.
 
Also new is AMSBIO’s Spike S1 RBD: ACE2 Inhibitor Screening Assay Kit. This key colorimetric assay kit is designed for screening and profiling inhibitors or neutralizing antibodies of the interaction between the Omicron variant SARS-CoV-2 Spike RBD and human ACE2. The new assay requires only a few steps to use. Firstly, SARS-CoV-2 Spike RBD (B.1.1.529, Omicron variant) is coated on a 96-well plate overnight. After washing and blocking, the protein is pre-incubated with an inhibitor or neutralizing antibody. Following incubation with Biotin-ACE2, the plate is treated with Streptavidin-HRP then addition of a colorimetric HRP substrate to produce color, which can be quenched and measured using a UV/Vis microplate reader.
 
Since the beginning of the global pandemic - several new SARS-CoV-2 variants have emerged, each with differing mutations that impact transmissibility, COVID-19 disease severity, and the effectiveness of vaccines. AMSBIO now offers a series of recombinant antigens and pseudotyped lentivirus with key Spike mutations in order to evaluate the efficacy of antibodies and vaccines. These products form part of a larger COVID-19 Tools for Research portfolio, including other high quality recombinant proteins, Spike pseudotyped lentivirus, and reagents for vaccine development and evaluation.
