Description | The antibody ZCB11 is a human mAb specific for SARS-CoV-2 Spike S1 protein. It targets viral receptor-binding domain specifically and neutralizes all SARS-CoV-2 variants of concern, especially with great potency against authentic Omicron and Delta variants. It is a promising broadly neutralizing antibody for biomedical interventions against pandemic SARS-CoV-2. |

Application Notes | The recombinant RBD and trimeric spike proteins derived from SARS-CoV-2 were diluted to final concentrations of 1 μg/mL, then coated onto 96-well plates and incubated at 4°C overnight. Plates were washed with PBST and blocked with blocking buffer at 37°C for 1 h. Serially diluted plasma samples or isolated monoclonal antibodies were added to the plates and incubated at 37°C for 1 h. Wells were then incubated with a secondary goat anti-human IgG labeled with HRP TMB substrate. OD at 450 nm was measured by SkanIt RE6.1 with VARIOSKAN Lux. Serially diluted plasma from healthy individuals or previously published monoclonal antibodies against SARS-CoV-2 were used as negative controls. |
