Fig. 1From: Comparative analysis of lipopolysaccharides of pathogenic and intermediately pathogenic Leptospira speciesComparative electrophoretic profile of lipopolysaccharide (LPS) extracted from pathogenic and intermediately pathogenic Leptospira strains. LPS was extracted from the pathogenic species, Leptospira interrogans serovar Copenhageni strain Fiocruz L1-130, and from the intermediately pathogenic species, Leptospira licerasiae serovar Varillal strain VAR010. LPS was isolated from both aqueous (AQ) and phenol (PH) layers of both species; profiles were determined by running 20 μl of LPS samples in SDS-PAGE followed by a periodic acid-silver staining method to detect LPS. Escherichia coli 055: B5 (E. coli) LPS was used as a standard LPS, and protein ladder (M) was used to localize the approximate the size of the LPS bandBack to article page
