Recombinant SARS-COV-2 S protein RBD (N501Y)
SARS-COV-2 S protein RBD (N501Y) is expressed from mammalian with a His tag and Avi at the C-terminal.
It contains Arg319 - Phe541 (N501Y).
|MOLECULAR WEIGHT||The protein has a predicted MW of 26.2 kDa. Due to glycosylation, the protein migrates to 36-40KDa based on Bis-Tris PAGE result.|
||Less than 1EU per ug by the LAL method.
|PURITY:||> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC
||Lyophilized from 0.22um filtered solution in 20mM PB (pH 7.4). 5 % trehalose is added as a protectant before lyophilization.|
|STORAGE||The product should be stored at -70℃ or -20℃.
|BACKGROUND||The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensin-converting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates this interaction. The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.|
