From
Recombinant Antibody
Specificity
This antibody specifically binds the amino acids 318-510 in the S1 domain of the SARS-CoV Spike protein (Urbani strain).
Alternative Names
Spike protein; S protein; SARS-CoV S protein; S glycoprotein; E2; Peplomer protein; Spike protein S1
UniProt
P59594
Immunogen
The original antibody was generated by immunizing a non human transgenic animal XENOMOUSE® IgG2k mice against S1 protein-Ig fragments (ectodomain) of the S Protein (Tor2).
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.The originally characterized antibody had a neutralizing titer 200TCID50 of 0.781μg/ml (Coughlin et at. 2006) and IC50 of 4.78μg/ml when incubated with S12–510- Fc recombinant protein (Coughlin et at. 2009). This antibody can also mildly bind the Sin845, GD01 and GZ0402 mutants of the Urbani 12-510 S1 sequence. (Elshabrawy et al. 2012). Other applications include ELISA.
