A novel, fast, and sensitive ME method was developed to analyze and differentiate the smooth (S) and rough (R) type bacterial endotoxin components labeled covalently with a fluorescent dye. The quantitative analysis of purified lipopolysaccharides, or partially purified samples from whole-cell lysates becomes possible with this method. Two groups with three sub-groups in the first group of S-type lipopolysaccharides can be classified based on the electrophoretic profiles. The LOD of the endotoxins from S- and R-type Gram-negative bacteria was found to be 2.6 ng and 6.9 ng, respectively. This method is capable to replace the commonly used SDS-PAGE combined with silver staining.
