Figure 2From: Sialic acid mediated transcriptional modulation of a highly conserved sialometabolism gene cluster in Haemophilus influenzae and its effect on virulenceT-SDS-PAGE analyses of LPS isolated from wild type (wt) strains Rd, 375 and 486 and their respective mutants. Panels (a) and (d) show profiles of LPS without (-) and with (+) neuraminidase treatment. The wt or mutant strains are indicated above each lane. Shown are: panels (a) and (b), strain Rd; panel (c), strain 375; panel (d), strain 486.Back to article page
