Comparison of the protein levels of FolP2 during the exponential phase in H37Ra, H37Ra folC(I43A), and H37Ra folC(I43T) strains, as indicated by western blot. Experiments were repeated at least three times, and representative results are shown. (a) Total protein (20 μg per lane) was separated by SDS-PAGE and stained by Coomassie brilliant blue. Lane M, the prestained protein marker. Lane 1, purified FolP2 protein. Lanes 2 and 3, total protein of H37Ra. Lanes 4 and 5, total protein of H37Ra folC(I43A). Lanes 6 and 7, total protein of H37Ra folC(I43T). (b) Western blot analysis of total protein immunoblotted with mouse antiserum with anti-FolP2. Lane 1, anti-FolP2 visualizing the purified FolP2 protein. Lanes 2 and 3, anti-FolP2 visualizing the total protein of H37Ra. Lanes 4 and 5, anti-FolP2 visualizing the total protein of H37Ra folC(I43A). Lanes 6 and 7, anti-FolP2 visualizing the total protein of H37Ra folC(I43T).
