Phase changes of cardiolipin vesicles mediated by divalent cations.
Small unilamellar vesicles were prepared from cardiolipin and produced the hexagonal II phase when dialyzed against CaCl2 or MgCl2. Upon removal of the cation by dialysis against EDTA large unilamellar vesicles were formed. The events of the transition from the lamellar to hexagonal phase and back to the lamellar phase are described.
