title: Partial purification and separation of H-2 antigens by free-flow preparative electrophoresis.
abstract: The membrane fraction of murine spleen cells was solubilized by autolysis in 0.25% potassium cholate and 3M potassium chloride, and the solubilized membrane components were fractionated by ultrafiltration and preparative free-flow electrophoresis. This procedure yielded partially purified fractions with enriched specific antigenic activities. The H-2Ka and H-2Da antigens were found to possess distinctly different electrophoretic mobilities.
