Overview
General Description
Recombinant Biotinylated SARS-COV-2 Spike S Trimer Protein is expressed from HEK293 with His tag and Avi tag at the C-terminal.It contains Val16-Glu1188.
Biotinylated
Yes
Specifications
Target
Spike S Trimer
Synonyms
S protein ; Spike glycoprotein ; S glycoprotein ; COVID-19
Accession
Species
SARS-COV-2
Exact Sequence
Val16-Glu1188
Molecular Weight
The protein has a predicted MW of 136.6 kDa. Due to glycosylation, the protein migrates to 140-170 kDa based on Tris-Bis PAGE result.
Activity
Immobilized Biotinylated SARS-COV-2 Spike S (Trimer) , His Tag at 2ug/ml (100ul/well) on the streptavidin precoated plate (5ug/ml). Dose response curve for Human ACE2, hFc Tag with the EC50 of 91.1ng/ml determined by ELISA. See testing image for detail.
Product Tag
C-His-Avi
Express System
HEK293
Purity
> 95% as determined by Tris-Bis PAGE
Endotoxin
Less than 1EU per ug by the LAL method.
Shipping, Reconstitution & Storage
Appearance
Lyophilized
Shipping Conditions
Shipped at ambient temperature.
Formulation
Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization.
Reconstitution
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability & 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.
