Figure 1From: Immunogenicity and protection of a Pasteurella multocida strain with a truncated lipopolysaccharide outer core in ducksLPS phenotypes. LPS extracted from the P. multocida WT strain, the mutant strain PMZ2 (ΔgatA*), two complemented strains, PMZ2 (pCZ57) and PMZ2 (pCZ58), and the control strain PMZ2 (pCZb5), were subjected to sodium dodecyl sulphate–polyacrylamide gel electrophoresis followed by silver staining. M refers to the protein marker.Back to article page
