SARS-CoV-2

Recombinant 2019 nCOV NP NTD Protein is expressed from E.coli with a His tag and Avi Tag at theN-terminal.;It contains Leu64-Ser180.

The protein has a predicted MW of 16.3kDa.Due to glycosylation, the protein migrates to 15-20 KDabased on Bis-Tris PAGE result.

Lyophilized from 0.22um filtered solution in PBS (pH 7.4).Normally 5 % trehalose is added as protectant before lyophilization.

N-His-Avi

> 95% as determined by Bis-Tris PAGE

Less than 1 EU per μg by the LAL method.

The product should be stored at -70℃ or -20℃.

Nucleocapsid protein (N) is the major viral structural component; its main function is to protect and encapsidate the viral RNA forming viral RNP complex. It is encoded by the S segment vRNA and is abundantly expressed in the cytoplasm of infected cells.
