Model of the monoclonal anti Vibrio cholerae O1, serotype Ogawa antibody–O-SP complexThis image depicts a model based on the X-ray structure of the Fab crystalline complex, with synthetic disaccharide that mimics terminus of bacterial O-PS.  Individual perosamine residues (various colors) are shown along with the light (light blue) and heavy chains (dark blue) of the Ab-variable domains, and the 2-O-methyl group-interface center (yellow).  Disaccharide synthesis from Section on Carbohydrates, LBC; crystallography performed at Institute Pasterur, Paris, France; taken from Villeneuve et al., PNAS, Vol. 97 (2000) 8433–8438Model of the monoclonal anti Vibrio cholerae O1, serotype Ogawa antibody–O-SP complexEnlarge
