  • Title: Precipitation of solubilized Na+/K+-ATPase by divalent cations.
    Author: Esmann M.
    Journal: Biochim Biophys Acta; 1988 May 09; 940(1):71-6. PubMed ID: 2835103.
    Abstract:
    A method for preparation of membranous fragments of pure and highly active shark rectal gland Na+/K+-ATPase by Mn2+ precipitation of C12E8-solubilized enzyme is described. The method is rapid and inexpensive, and yields enzyme with a specific Na+/K+-ATPase activity of up to 1800 mumol/mg per h at 37 degrees C. The influence of the detergent/protein and lipid/protein ratios on the yield of membrane bound enzyme is described.
