Recombinant monoclonal antibody to Norovirus GII.4. Manufactured using AbAb’s Recombinant Platform with variable regions (i.e. specificity) from the phage display antibody 12A11.
Immunogen: A phage-displayed antibody library was generated from peripheral blood of healthy persons. The original antibody was isolated by screened using purified virus-like particles (VLPs) of strain Narita 104 (r104, genogroup II, genotype 4).
Specificity: The antibody is specific for Norovirus GII.4. The antibody shows intra-genogroup cross-reactivity to genotypes 1, 3–7, 12, and 14 of genogroup II.
Application Notes: The specificity of the original format of the antibody was confirmed by ELISA analysis. The blocking activity of the antibody against the interaction of homotypic VLPs with histo-blood group antigens were also assessed as an alternative to neutralization assay. The antibody showed a low blocking activity.
