Background:Coronavirus N protein is required for coronavirus RNA synthesis, and has RNA chaperone activity that may be involved in template switch. Nucleocapsid protein is a most abundant protein of coronavirus. N protein packages the positive strand viral genome RNA into a helical ribonucleocapsid (RNP) and plays a fundamental role during virion assembly through its interactions with the viral genome and membrane protein M. Plays an important role in enhancing the efficiency of subgenomic viral RNA transcription as well as viral replication. Because of the conservation of N protein sequence and its strong immunogenicity, the N protein of coronavirus is chosen as a diagnostic tool.

Concentration:

Activity:Not validated for activity

Sequence:Met1-Ala419

Purity: > 95% as determined by reducing SDS-PAGE.

Formulation:Lyophilized from sterile PBS, pH 7.4., 5% trehalose, 5% mannitol, 0.01% Tween 80.
Normally 5%-8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.

Reconstitution:It is recommended that sterile water be added to the vial to prepare a stock solution of 0.5 mg/mL. Concentration is measured by UV-Vis.

Endotoxin:< 10 EU/mg of the protein as determined by the LAL method.

Calculated MW:49.4 kDa
