Source : HEK293
Species : COVID-19
Tag : His
Form : Lyophilized from sterile PBS, pH 7.4.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Bio-activity : Immobilized human ACE2 protein (Fc tag) at 2 μg/mL (100 μL/well) can bind Recombinant SARS-CoV-2 (BA.2.75.2) Spike RBD Protein (His Tag), the EC50 is 20-60 ng/mL.
Molecular Mass : The recombinant SARS-CoV-2 Spike RBD consists of 234 amino acids and predicts a molecular mass of 26.63 kDa. As a result of glycosylation, it migrates as an approximately 35.78 kDa band in SDS-PAGE under reducing conditions.
Protein Length : Arg319-Phe541
Endotoxin : < 1.0 EU per μg protein as determined by the LAL method.
Purity : > 95 % as determined by SDS-PAGE. > 95 % as determined by SEC-HPLC.
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 lyophilized powder in sterile water to 100-200 ug/ml, and further dilute with other solvents. The dissolved protein 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.
