FIG. 2.
Sodium dodecyl sulfate-polyacrylamide gel electrophoresis gel strips of the various SARS-CoV NP protein constructs after purification. Almost all constructs appear as a single band in the gel strips, and for the few exceptions, the purity of the main band exceeds 90%. Lanes are labeled in the following order: M, light molecular mass marker; 1, NP1-181; 2, NP45-181; 3, NP45-247; 4, NP181-365; 5, NP248-365; 6, NP248-422; 7, NP45-365; 8, Sumo-1-FL.
