Relevance
Nucleocapsid protein is a most abundant protein of coronavirus on the helical nucleocapsid of coronaviruses. N protein of SARS CoV-2 ab273530 is a structural protein required for RNA synthesis, and has RNA chaperone activity that may be involved in template switch. N protein enters the host cell with the viral RNA to facilitate its replication and process the virus particle assembly and release. N protein is a highly immunogenic phosphoprotein also implicated in modulating cell signalling pathways. Coronavirus nucleocapsid proteins localize to the cytoplasm and the nucleolus, a subnuclear structure, in both virus-infected primary cells and in cells transfected with plasmids that express N protein.

Western blot - Recombinant Human coronavirus SARS-CoV-2 nucleocapsid protein (His tag) (ab273530)
Samples
Lanes 1 & 3: Recombinant Human coronavirus SARS-CoV-2 Nucleocapsid Protein (His tag) (ab273530) (0.2 µg)
Lanes 2 & 4: Recombinant Human coronavirus SARS-CoV-2 Nucleocapsid Protein (His tag) (ab272107) (0.2 µg)
Green: Rabbit monoclonal [EPR24334-118] to SARS-CoV-2 nucleocapsid protein (ab271180)
Red: Mouse monoclonal [HIS.H8] to 6X His tag® (ab18184)
Lanes 1 & 2: Green - ab271180 observed at 50 kDa.
Lanes 3 & 4: Red - loading control Mouse anti-6x HisTag observed at 50 kDa.
ab271180 was shown to react with SARS-CoV-2 nucleocapsid protein in Western blot. Membranes were blocked in 3% milk before incubation with ab271180 and Mouse anti-6x HisTag overnight at 4 °C at a 1/1000 dilution. Blots were incubated with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) secondary antibodies at 1/20000 dilution for 1 h at room temperature before imaging.
