Human Coronavirus (229E) Nucleocapsid Protein, His tag, E. coli

There are six strains of coronavirus within two subgroups that infect humans. The strains of human coronaviruses that commonly infect people worldwide include 229E and NL63 in the Alpha subgroup and OC43 and HKU1 in the Beta subgroup. Nucleocapsid protein (NP) 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. This product is composed of a DNA sequence encoding Human Coronavirus (229E) NP and a polyhistidine tag at the C-terminus.
