SARS-CoV-2 Nucleocapsid Protein (N-protein) is a structural protein that binds to the coronavirus RNA genome, thus creating a shell (or capsid) around the enclosed nucleic acid. It is the most abundant protein for coronavirus. Recombinant N-protein was expressed in E. coli with the 8XHis tag and AviTag at the N-terminus and site-specifically biotinylated at AviTag with BirA biotin ligase.

Catalog number: COVNB-301

Expression host: Escherichia coli (E. coli). 

Species: SARS-CoV-2

Expressed Region of N protein: Met1 – Ala419

Predicted molecular weight: 49 kDa

Tags: His, AviTag

Purity: > 90% as analyzed by SDS-PAGE

Storage buffer: 10 mM Tris-HCl, pH 7.5, 100 mM NaCl, 1 mM DTT and 50% Glycerol.
