Identification of purified nucleocapsid protein and QDs-conjugated N protein. (a) Purified nucleocapsid protein isolated by 12% SDS-PAGE. (b) Purified nucleocapsid protein isolated by Western blot. Lane 1: Protein Ladder. Lane 2: N protein reacted with anti-His-Tag mouse monoclonal antibody (5C3). (c) QDs and conjugates identified by agarose gel electrophoresis. (d) Fluorescence spectrum of QDs and conjugates. (e–h) Size distribution and ζ potential distribution of QDs and conjugates, as measured by Malvern Zetasizer.
