Figure 6. . . . . . Sodium dodecyl sulfate-polyacrylamide gel electrophoresis and Western blot analysis of a novel coronavirus, dromedary camel coronavirus UAE-HKU23, discovered in dromedaries of the Middle East, 2013.Nucleocapsid protein was expressed in Escherichia coli. M, protein molecular-mass marker; kDa, kilodaltons. Lanes: 1, non-induced crude E. coli cell lysate; 2, induced crude E. coli cell lysate of DcCoV UAE-HKU23 nucleocapsid protein; 3, purified recombinant DcCoV UAE-HKU23 nucleocapsid protein; 4, dromedary camel serum sample strongly positive for antibody against nucleocapsid protein; 5, dromedary camel serum sample moderately positive for antibody against nucleocapsid protein; 6 and 7: dromedary camel serum sample negative for antibody against nucleocapsid protein.
