SARS-CoV-2 Nucleocapsid Protein, E. coli
Endotoxin level :
<0.1 EU per 1 μg of the protein by the LAL method.
>95% as determined by SDS-PAGE.
The protein was lyophilized from a solution containing 1X PBS, 10 mM potassium carbonate, pH 7.4.
It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
Lyophilized protein should be stored at -20°C. Upon reconstitution, protein aliquots should be stored at -20°C or -80°C.
Please use within one month after protein reconstitution.
