  • Title: Isolation and characterization of plasma membranes from rabbit skeletal muscle.
    Author: Rock E, Lefaucheur L, Chevallier J.
    Journal: Biochem Biophys Res Commun; 1984 Aug 30; 123(1):216-22. PubMed ID: 6089792.
    Abstract:
    An improved procedure was developed for the isolation of skeletal muscle plasma membranes. This method includes a DNAse treatment of the homogenate prior to the isolation of membranes by differential and sucrose gradient centrifugation techniques. We obtained two light fractions which were highly enriched in many biochemical and chemical plasma membrane markers. These fractions were shown to be mostly inside-out vesicles containing a Ca2+-ATPase activity. These results suggested that this enzyme could participate in the extrusion of calcium ions from the muscle cells.
