title: Increased resolution of lipopolysaccharides and lipooligosaccharides utilizing tricine-sodium dodecyl sulfate-polyacrylamide gel electrophoresis.
abstract: We utilized the recently described tricine-sodium dodecyl sulfate-polyacrylamide gel electrophoresis (TSDS-PAGE) system to study the lipooligosaccharides (LOS) and lipopolysaccharides (LPS) of gram negative bacteria. TSDS-PAGE resulted in a high degree of resolution of LOS and LPS in the 'mini-gel' format. TSDS-PAGE resulted in the LOS and LPS migrating as a function of their Mr during electrophoresis and allowed estimation of Mr from a protein standard. Several species of LOS were analyzed. The newly described procedure allowed a more rapid and accurate analysis of LOS and the core region of LPS.
