[Effect of sodium dodecyl sulfate on biological membranes].

Effect of sodium dodecyl sulfate (SDS) on yeast cells resulting in the cellular proteins release from the cells was examined. The influence of pH, ionic strength, the agent concentration and the cells lipids content on the proteins extraction degree was studied. It is assumed that the proteins release is due to the plasma membrane solubilization under the surfactant treatment.
