Optional Service: Optional requirements on this protein
Product Overview :
A DNA sequence encoding the SARS-CoV-2 (2019-nCoV) Spike RBD(P337S)-His Recombinant Protein (YP_009724390.1) (Arg319-Phe541(P337S)) was expressed in HEK293 cells with a polyhistidine tag at the C-terminus.
Source :
HEK293
Species :
COVID-19
Tag :
His
Predicted N Terminal :
Arg319
Form :
Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Molecular Mass :
The recombinant SARS-CoV-2 (2019-nCoV) Spike RBD(P337S)-His Recombinant Protein consists of 234 amino acids and predicts a molecular mass of 26.5 kDa.
Protein length :
Arg319-Phe541
Endotoxin :
< 1.0 EU per μg protein as determined by the LAL method.
Purity :
> 80 % as determined by SDS-PAGE.
Stability :
Samples are stable for up to twelve months from date of receipt at -20°C to -80°C
Storage :
Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution :
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.25 ug/ul. Centrifuge the vial at 4ºC before opening to recover the entire contents.
Shipping :
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
