Clone No. | 256 |
From | Recombinant Antibody |
Isotype | Engineer antibody |
Application | NTRL, ELISA |
Species Reactivity | SARSCoronavirus |
Basic Information | |
Specificity | This antibody specifically binds the amino acids 472 and 480 in the S1 domain of the SARS- CoV Spike protein (Tor2 and GD03). |
Alternative Name | Spike protein; S protein; SARS-CoV S protein; S glycoprotein; E2; Peplomer protein; Spike protein S1 |
UniProt | P59594 |
Immunogen | The original antibody was produced by panning against GD03-RBD-C9, two non-immune human Ab phage display libraries and neutralizing activity was tested against pseudotyped viruses. |
Application Notes | This antibody inhibits the association of SARS-CoV S protein to the angiotensin- converting enzyme 2 (ACE2) receptor by binding to specific amino acids on the S1 domain of the spike protein of the virus. 256-IgG1 was capable of neutralizing both the mutations of the spike protein at D480A and D480G. It also neutralized Tor2 and marginally neutralized GD03. Neither of the antibodies 11A nor 80R competed with 256 IgG1 for binding to Tor2 suggesting that the binding epitope of 256 was different from that of 80R and 11A (Sui et. al, 2008) |
