背景介绍 Nucleoprotein (ORF9a) packages the positive-strand viral RNA genome into a helical ribonucleocapsid (RNP) during virion assembly through its interactions with the viral genome and membrane protein M. 产品介绍 Recombinant ORF9b, full length, encompassing amino acids 1-97(end). This recombinant protein corresponds to SARS-CoV-2 accessory protein ORF9b. It was expressed in E.coli and contains an N-terminal GST tag and a prescission protease cleavage site. The recombinant protein is >90% pure following GST affinity purification.
