In the present work combined glycan-, lectin-, and immunoblotting of isolated brain and kidney membranes shows that the alpha and beta subunits of Na,K-ATPase are the most abundant glycoproteins. Further, Datura stramonium and Galanthus nivalis agglutinins recognize the Na,K-ATPase subunits in a mutually exclusive manner in membranes from human, rabbit and rat brain or human, rabbit, rat, pig a...

A method for the preparative isolation of peroxisomes from the livers of rat, guinea pig, and mouse, and also from rat kidney is described. The light mitochondrial fraction, i.e., particles sedimenting between 33,000 and 250,000g-min, or the postnuclear supernatant of liver or kidney, is subjected to a 20-50% Metrizamide density gradient ultracentrifugation in a vertical rotor. After centrifuga...
