Immunoblot reactivity of isogenic gml mutants of K. pneumoniae O1 strain. The wild-type (gml–) strain Kp4 was trans-complemented with the cloned gml operon or the empty vector (as control). Separated LPS molecules were reacted with monoclonal antibodies specific to different galactan structures as shown: (A) anti-gal-II mAb 5C10, (B) anti-gal-I mAb 1F11, (C) anti-gal-III mAb 5A4. Serotype O2 (PCM-27) and O3 (PCM-11) strains were used as controls (lanes 1 and 2). Lane description: 1, PCM-27 (O2gml+), 2, PCM-11 (O3, control), 3, Kp4 (O1gml–), 4, Kp4/pSU2718 (O1gml–), 5, Kp4/pKP100 (O1gml+).
