Description |
Recombinant SARS-CoV-2 Spike RBD (Omicron BA.2.38) Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Arg319-Phe541(G339D, S371F, S373P, S375F, T376A, D405N, R408S, K417T, N440K, S477N, T478K, E484A, Q493R, Q498R, N501Y, Y505H). |
Background |
The ongoing coronavirus disease 2019 (COVID-19) pandemic has prioritized the development of small-animal models for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The resulting mouse-adapted strain at passage 6 (called MASCp6) showed increased infectivity in mouse lung and led to interstitial pneumonia and inflammatory responses in both young and aged mice after intranasal inoculation. Deep sequencing revealed a panel of adaptive mutations potentially associated with the increased virulence. In particular, the N501Y mutation is located at the receptor binding domain (RBD) of the spike protein. |
Manufacturers Product Type |
Recombinant Protein |
Endotoxin |
Less than 1EU per μg by the LAL method. |
Molecular Weight |
The protein has a predicted MW of 26.07 kDa. Due to glycosylation, the protein migrates to 35-45 kDa based on Tris-Bis PAGE result. |
Stability and Storage |
-20 to -80°C for 12 months as supplied from date of receipt.;-80°C for 3-6 months after reconstitution.;2-8°C for 2-7 days after reconstitution.;Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles. |
Shipping |
Shipped at ambient temperature. |
Formulation |
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
Tag Information |
C-His |
Formulation |
Supplied as 0.22μm filtered solution in PBS (pH 7.4). |
