title: [Extraction of highly active preparations of "soluble" Na+, K+-ATPase from different membrane stuctures of the brain].
abstract: A successive treatment with sodium iodide and digitonin of the myeline, microsome and synaptosome fractions of the cattle brain tissue resulted in obtaining the preparations of "soluble", Na+, K+-ATPase with a rather high specific activity non-containing practically Mg2+-dependent ATPase. To estimate the degree of these preparations structural heterogeneity they were subjected to analytical ultracentrifugation and disc-electrophoresis in polyacrylamide gel. The data obtained suggest an insignificant degree of heterogeneity for the "soluble" Na+, K+-ATP-ase preparations.
