Assay Data
Tris-Bis PAGE

SARS-COV-2 Nucleocapsid on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.


Nucleocapsid protein (N) is the major viral structural component; its main function is to protect and encapsidate the viral RNA forming viral RNP complex. It is encoded by the S segment vRNA and is abundantly expressed in the cytoplasm of infected cells.
