VRP-3105 Recombinant SARS-CoV-2 Nucleocapsid (N) Protein $100

Recombinant SARS-CoV-2 Nucleocapsid (N) Protein

Product Name: Recombinant SARS-CoV-2 Nucleocapsid (N) Protein
Catalog #:  VRP-3105
Manufacture:  LD Biopharma, Inc.

The beginning of 2020 has seen the emergence of COVID-19 outbreak caused by a novel Coronavirus: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Viral Nucleocapsid (N) protein (419aa) protein has been successfully used as immunogenic reagent for immunological / serological studies. This recombinant Nucleocapsid gene was codon optimized using gene synthesis technology, and was expressed in E. coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.

Gene Symbol:  Nucleocapsid ( N ) 
Accession Number:  MN908947
Species:  SARS-Cov-2
