Recombinant SARS-Cov-2 Spike RBD (Omicron BA.2.12.1) Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Arg319-Phe541(G339D, S371F, S373P, S375F, T376A, D405N, R408S, K417N, N440K, L452Q, S477N, T478K, E484A, Q493R, Q498R, N501Y, Y505H) [Accession | QHD43416.1]. |
分子量大小(Molecular Weight)
|
The protein has a predicted MW of 26.09 kDa. Due to glycosylation, the protein migrates to 38-48 kDa based on Bis-Tris PAGE result. |
纯度(Purity)
|
> 95% as determined by Bis-Tris PAGE |
内毒素(Endotoxin)
|
Less than 1EU per μg by the LAL method. |
制剂(Formulation)
|
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
重构方法(Reconstitution)
|
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
存储(Storage)
|
-20 to -80°C for 12 months as supplied from date of receipt. |

Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
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.
