FIGURE 2.
Purification of FlgG-His6 and immunoblotting analysis. FlgG-His6 (A) and FlgG-His6(T75S) or FlgG-His6(T75Y) (B) purified via affinity chromatography from C. jejuni and Western blotted using anti-His6 and anti-FlgG antibodies to show purity. Crude cell extracts (CCE) and purified FlgG from indicated strains were resolved by SDS-PAGE and stained with Coomassie (top panel), blotted with anti-polyhistidine (middle panel), and anti-FlgG M69 murine antiserum (bottom panel) (23). Purified FlgG is seen along with additional smaller bands assumed to be FlgG degradation products.
