Source

SARS-CoV-2 Nucleocapsid protein, His Tag (NUN-C5227) is expressed and secreted by human 293 cells (HEK293). It contains AA Met 1 - Ala 419 (Accession # QHO62115.1).
Predicted N-terminus: Met 1

Molecular Characterization

Online(Met 1 - Ala 419) QHO62115.1Development Suggestion
This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 47.3 kDa. The protein migrates as 60-65 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 1.0 EU per μg by the LAL method.

Purity

>95% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
