已发表文献
Coronaviruses are commonly comprised of four structural proteins: Spike protein (S), Envelope protein (E), Membrane protein (M) and Nucleocapsid protein (N) . The SARS-CoV-2 S protein is a glycoprotein that mediates membrane fusion and viral entry. The S protein is homotrimeric, with each ~180-kDa monomer consisting of two subunits, S1 and S2 . The RBD of SARS-CoV-2 binds a metallopeptidase, angiotensin-converting enzyme 2 (ACE-2).

Recombinant SARS-CoV-2 Spike RBD (Omicron BQ.1.1) Protein is expressed from Expi293 with His tag at the C-terminal. It contains Arg319-Phe541(G339D, R346T, S371F, S373P, S375F, T376A, D405N, R408S, K417N, N440K, K444T, L452R, N460K, S477N, T478K, E484A, F486V, Q498R, N501Y, Y505H). |
|
分子量 |
Approximately 25.98 kDa. Due to glycosylation, the protein migrates to 35-43 kDa based on Tris-Bis PAGE result. |
|
纯度 |
> 95% as determined by SDS-PAGE and HPLC. |
|
活性 |
ELISA Data：Immobilized SARS-CoV-2 Spike RBD (Omicron BQ.1.1) , His Tag at 0.5μg/ml (100μl/Well) on the plate. Dose response curve for Human ACE2, hFc Tag with the EC50 of 15.8ng/ml determined by ELISA. |
|
内毒素 |
< 1.0 EU per 1μg of the protein by the LAL method. |
|
制剂 |
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). |
|
复溶 |
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water. |
储存条件
The product should be stored at -25~-15℃.
1 month, 2 ~8 °C under sterile conditions after reconstitution.
3 months, -25~-15℃ °C under sterile conditions after reconstitution.
Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
注意事项
1.Please operate with lab coats and disposable gloves，for your safety。
2.This product is for research use only.
