Recombinant COVID-19 NSP8 protein, His-tagged

• Cat.No.: NSP8-198V
• Product Overview: Recombinant COVID-19 NSP8 protein (Ala1-Gln198) was fused to his-tag at the N-terminus and expressed in E.coli.

Specification

• Species: COVID-19
• Source: E.coli
• Tag: His
• ProteinLength: Ala1-Gln198
• Description: NSP8, forms a hexadecamer with nsp7 (8 subunits of each) that may participate in viral replication by acting as a primase. Alternatively, may synthesize substantially longer products than oligonucleotide primers. To ultimately combat the emerging COVID-19 pandemic, it is desired to develop an effective and safe vaccine against this highly contagious disease caused by the SARS-CoV-2 coronavirus. By investigating the entire proteome of COVID-19, six proteins, including the S protein and five non-structural proteins (nsp3, 3CL-pro, and nsp8-10) were predicted to be adhesins, which are crucial to the viral adhering and host invasion. The S, nsp3, and nsp8 proteins were also predicted by Vaxign-ML to induce high protective antigenicity.
• Predicted N Terminal: Met
• Form: Delivered as bulk protein in a 0.2 μm filtered solution of 20 mM Tris, 250 mM NaCl, pH8.5 with glycerol as protectant.
• Molecular Mass: The protein has a calculated MW of 23.9 kDa. The protein migrates as 22-25 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.
• Storage: Please avoid repeated freeze-thaw cycles.
