|Cat.No. :||Spike-10VB Optional Service: Optional requirements on this protein|
|Product Overview :||Biotinylated Recombinant COVID-19 Spike NTD protein(YP_009724390.1) (Met1-Ser305) was expressed in HEK293, fused with a C-terminal polyhistidine tag followed by an AVI tag.|
|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 S1 NTD consists of 314 amino acids and predicts a molecular mass of 35.89 kDa.|
|Protein length :||Met1-Ser305|
|Endotoxin :||< 1.0 EU per μg protein as determined by the LAL method.|
|Purity :||> 90 % as determined by SDS-PAGE.|
|Storage :||Samples are stable for up to twelve months from date of receipt at -20°C to -80°C
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 to reconstitute the OsrhVEGF lyophilized powder in sterile water to 100-200 ug/ml, and further dilute with other solvents. The dissolved OsrhVEGF can be stored at 4°C for 2-7 days and should be used up as soon as possible. If not in use for a short time, please store at -20°C.|
