COVID-19 (SARS-CoV-2) Nucleocapsid protein (NP)

Packing and cost: 1 mg - 300$ / 100 mg - 2500$ / 1000 mg - 150 000$
Name. Nucleocapsid protein, N protein, NP protein SARS-CoV-2 (COVID-19).

 

Specification. Recombinant N protein was purified from E.coli cells. It contains AA 1-419 fused to poly-his tag.

 

Purity. >95% by SDS-PAGE under reducing and non reducing conditions. The protein migrates as 48-50 kDa.

 

Special features. N protein in ELISA reacted with most of SARS-CoV-2 (COVID-19) patient sera and did not react with normal patient sera. Our SARS-CoV-2 N protein is already used in the manufacture of IVD ELISA kits.

 

Formulation. Lyophilized powder or white tablet.

 

Storage. N protein should be stored at lyophilized state at -20°C or lower.
Application. ELISA, WB.

Purity >95%

SARS-CoV-2 NP protein was separated on a 12.5% PAGE gel under reducing (R) and non reducing (nR) conditions. The gel was stained with “Instant Blue coomassie protein stain” with sensitivity - 5ng per band. The amount of loaded protein were 2 and 40 μg.
