Figure 3From: Outer membrane protein P4 is not required for virulence in the human challenge model of Haemophilus ducreyi infection Specificity of anti-OmpP4 antiserum. Western blot probed with polyclonal antisera from mice inoculated with purified, recombinant OmpP4. Lane 1, purified recombinant OmpP4; lane 2, 35000HP whole cell lysates. The predicted molecular weight of recombinant, histidine-tagged OmpP4 is 29.2Â kDa.Back to article page
