Description | This is a anti-SARS-CoV-2 Spike S1 mouse antibody 17B10 recoginzing receptor-binding domain ridge. 17B10 broadly neutralizes infectious SARS-CoV-2 from ancestral strains to Delta variants. It is highly potent in microneutralization assay against infectious SARS-CoV-2 variants. |
Clonality | Monoclonal |
Host Species | Mouse |
Target Species | SARS-CoV-2 |
Cross Reactivity | Alpha, Lambda, Delta |
Immunogen | The RBD (residues 319-533) of Wuhan-Hu-1 strain (GenBank: NC_045512.2) with a 6xHis-tag. |
Epitope | The binding surface of 17B10 is formed primarily by residues 455−458 and residues 473−493, particularly with residues 458, 477, 478, 486, 487, and 489 as the key contacting sites |
Neutralization Mechanism | The antibody targets the tip of the receptor binding motif in the RBD-up conformation. |

Application | ELISA; BLI; Neut |
Application Notes | ELISA: Serially diluted mouse mAbs were then added and were incubated at room temperature for 1 h. Bio-layer interferometry (BLI): The RBD loaded SA biosensors were dipped in 17B10 mAb (50 µg/mL in 1X Kinetics Buffer) for 600 s. Neutralization assay (Neut): Serially diluted mAbs were incubated with SARS-CoV-2 pseudovirus particles bearing the original D614 spike at 37°C for 1 h and were then incubated with HEK293-ACE2 target cells in Poly-D-lysine coated 384-well plates for 2 days. |
