As one of the most abundantly expressed and immunogenic SARS-CoV-2 proteins, the N protein is a primary target for serology assays, COVID-19 diagnostics, and pan-coronavirus vaccine development. The Omicron (B.1.1.529) variant N protein carries R203K and G204R mutations that alter RNA binding and phase-separation behaviour.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cspan class=\"bhp-cat-pill\"\u003eE. coli Expression\u003c\/span\u003e\n\u003cp\u003eSARS-COV-2 Nucleocapsid (B.1.1.529\/Omicron) is supplied as a recombinant protein with C-His.
