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).

Accession

QHD43416.1

表达区间及表达系统

Recombinant SARS-CoV-2 Spike RBD (Omicron BF.7/BA.4.6) 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, L452R, S477N, T478K, E484A, F486V, Q498R, N501Y, Y505H).

分子量

Approximately 25.99 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 DataImmobilized SARS-CoV-2 Spike RBD (Omicron BF.7/BA.4.6) , 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 glovesfor your safety

2.This product is for research use only.
