Sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS-PAGE) showing the expression and the purification of the viral proteins using N-terminal His-tag. (A) Cef, Pin, MRH, Y00H, Y00G, and DexA proteins were collected in the soluble fraction, evident by the presence of bands of correct molecular weight in the elusion fraction. (B) MotB, RpbA, SegF, Y01A, ComCα, and Valyl proteins were expressed into the inclusion body, evident by the absence of bands of correct molecular weight in the elusion fraction and the presence of the bands in the insoluble fraction. M, Marker; FT, Flow-through fraction; W, Wash fraction; E, elusion fraction; Ins, Resolublized cell debris containing insoluble protein.
