  • Applications
  • Flow Cytometry (Transfected cell)
  • Flow Cytometry (Transfected cell)
  • Flow cytometry (transfected cell) analysis of 293T-SARS-CoV-2 spike cells were treated with SARS-CoV-2 S recombinant human monoclonal antibody, clone 7F7 (Cat # RAB01068-M01J). This antibody efficiently bound to 293T- SARS-CoV-2 spike cells.
  • Inhibition Assay
  • Inhibition Assay
  • Protein receptor-binding inhibition assay of spike-His protein was treated with SARS-CoV-2 S recombinant human monoclonal antibody, clone 7F7 (Cat # RAB01068-M01J), and then added into 293T-ACE2 cells. Data were analyzed by flow cytometer. Binding affinity of spike-His protein to ACE2 is totally blocked by this antibody.
  • Neutralization
  • Neutralization
  • Neutralization analysis of pseudovirus was treated with SARS-CoV-2 S recombinant human monoclonal antibody, clone 7F7 (Cat # RAB01068-M01J), and then added into 293T-ACE2 cells. Luciferase activity was measured 48 hours post infection.
  • Neutralization
  • Neutralization
  • Neutralization analysis of variant pseudovirus was treated with SARS-CoV-2 S recombinant human monoclonal antibody, clone 7F7 (Cat # RAB01068-M01J), and then added into 293T-ACE2 cells. Luciferase activity was measured 48 hour post infection.
  • Neutralization
  • Neutralization
  • Cytopathic effect (CPE) based live virus neutralization analysis with human IgG1 isotype control and SARS-CoV-2 S recombinant human monoclonal antibody, clone 7F7 (Cat # RAB01068-M01J). The antibody solutions (100 uL) were mixed in 1:1 (v/v) with suspension containing 200 TCID50 of SARS-CoV-2 virus.
  • Antibody Kinetics
  • Antibody Kinetics
  • Antibody kinetics with SARS-CoV-2 S recombinant human monoclonal antibody, clone 7F7 (Cat # RAB01068-M01J) and data were analyzed by biacore surface plasmon resonance.
  • Epitope Mapping
  • SARS-CoV-2 S1+S2 domain (residues 16-1213): positive
    SASRS-CoV-2 S1 domain (residues 1-674): positive
    SARS-CoV-2 receptor binding domain (residues 319-541): positive
    SARS-CoV-2 core domain + receptor binding subdomain (residues 387-516): positive
    SARS-CoV-2 receptor-binding motif (residues 438-505): positive
    Data were analyzed by indirect ELISA.
  • Enzyme-linked Immunoabsorbent Assay
  • Enzyme-linked Immunoabsorbent Assay
  • ELISA analysis coated mucin (100 ug/mL) with SARS-CoV-2 S recombinant human monoclonal antibody, clone 7F7 (Cat # RAB01068-M01J).
  • Neutralization
  • Neutralization
  • In in vivo neutralization analysis, hamsters received 2 doses of SARS-CoV-2 S recombinant human monoclonal antibody, clone 7F7 (Cat # RAB01068-M01J) by intraperitoneal injection and then were infected with 3 doses pseudovirus through intanasal injection. Lung tissues were collected one day post last dose pseudovirus treatment. Luciferase gene expression level was detected by QPCR.
  • Neutralization
  • Neutralization
  • In in vivo nasal prophylaxis neutralization analysis. Hamsters were infected with either B.1.1.28.1 (upper panel) or B.1.617.2 (lower panel) variant spike pseudovirus 2 hours after receiving SARS-CoV-2 S recombinant human monoclonal antibody, clone 7F7 (Cat # RAB01068-M01J). Lung tissues were collected one day after the last dose of pseudovirus treatment. Luciferase gene expression level was detected by qPCR.
