title: Electrophoretic properties of sodium dodecyl sulfate and related changes in its concentration in SDS-polyacrylamide gel electrophoresis.
abstract: Sodium dodecyl sulfate(SDS) in a protein sample solution migrates in SDS-polyacrylamide gel electrophoresis as a band with a mobility higher than those of protein bands. Behind this band, which is mostly composed of SDS micelles, SDS concentration is raised uniformly in a gel column as a result of the retardation effect of the gel matrix on SDS micelles. Electrophoretic patterns of SDS were obtained when SDS was omitted from various portions of the gel electrophoretic system.
