SARS-COV-2 Spike RBD Protein
|SOURCE||SARS-COV-2 Spike RBD Protein is expressed from mammalian with a hFc tag at the C-terminal.
It contains Arg319 - Phe541.
|MOLECULAR WEIGHT||The protein has a predicted MW of 51.7kDa. Due to glycosylation, the protein migrates to 55-70KDa based on the 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 PBS (pH 7.4). 5% trehalose is added as a protectant before lyophilization.|
|STORAGE||The product should be stored at -70℃ or -20℃.
||Centrifuge tubes before opening. Reconstituting to a concentration of more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.|
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.
