FIG 7.

Electrophoretic profiles of LPS from B. cenocepacia K56-2, J2315, K56-2, and K56-2 deletion mutants and complements. LPS was prepared as described in Materials and Methods. A total of 1.0 μg LPS was loaded in each lane of a 16.5% polyacrylamide gel in a Tricine-SDS system and developed by silver staining as described in Materials and Methods. Please note that the white line between lanes 3 and 4 indicates that a lane was removed from the original gel, since the data were not presented for the strain in Results.
