Endotoxin: <1.0 EU per μg protein as determined by the LAL method. Activity: Testing in progress.
Protein Construction: A DNA sequence encoding the NCP-CoV(2019-nCoV) Nucleocapsid Protein was expressed with a polyhistidine tag at the C-terminus.
Expressed Host: Baculovirus-Insect Cells
Species: 2019-nCoV
Predicted N Terminal: Met
Molecule Mass: The recombinant NCP-CoV(2019-nCoV) Nucleocapsid Protein (His tag) consists of 430 amino acids and predicts a molecular mass of 47.08 kDa.
Formulation: Lyophilized from sterile 20mM Tris, 500mM NaCl, pH8.0, 10% glycerol.
Please contact us for any concerns or special requirements.
Normally 5 % – 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the hard copy of CoA.
Shipping: Generally, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Regulatory/ Restrictions: For research use only.
