Fig 4. Fluorescence against surface capsule is greatly diminished in the TIGR4 spxB mutant.

Fig 4

Capsule production was detected using fluorescence microscopy using primary antibodies against type 2 or 4 capsules with a fluorescent secondary (green) and DAPI stain to detect DNA (blue). Three representative images of TIGR4 (A) and the spxB (B), lctO (C), and double spxB lctO (D) mutants in the TIGR4 background and D39 (E) and the spxB (F), lctO (G), and double spxB lctO (H) mutants in the D39 background are shown.
