Background
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.
Description
Recombinant SARS Spike RBD Protein is expressed from Expi293 with His tag and Avi tag at the C-terminal. It contains Arg306-Phe527.
Target
Spike RBD
Species
SARS
Gene/Protein ID
P59594
Exact Sequence
Arg306-Phe527
Molecular Weight
The protein has a predicted MW of 27.9 kDa. Due to glycosylation, the protein migrates to 36-46 kDa based on the Tris-Bis PAGE result.
Activity
Immobilized SARS Spike RBD, His Tag at 2ug/ml (100ul/well) on the plate. Dose response curve for Human ACE2, hFc Tag with the EC50 of 39.0ng/ml determined by ELISA. See testing image for detail.
Tag
C-His-Avi
Express System
Expi293
Purity
> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Endotoxin
Less than 1EU per ug by the LAL method.
Formulation
Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as a protectant before lyophilization.
Stability and Storage

Reconstituted protein stable at -80 C for 12 months, 4 C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.

Shipping
Shipped at ambient temperature.
Reconstitution

Centrifuge tubes before opening. Reconstituting to a concentration of more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
