Biological Activity

ELISA plate pre-coated by 2 μg/ml (100 μl/well) SARS-CoV-2 (2019-nCoV) Nucleocapsid, His Tag protein can bind Anti-SARS-CoV-2 Nucleocapsid Antibody in a linear range of 0.122-15.625 ng/ml.

Storage

Store at -20°C to -80°C for 12 months in lyophilized form. After reconstitution, if not intended for use within a month, aliquot and store at -80°C (Avoid repeated freezing and thawing).Lyophilized proteins are shipped at ambient temperature.

Reconstitution

It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
