phosphatidylserine has been the subject of much of the study in this area. Phosphatidylserine …

… of phosphatidylserine (PS) vesicles ( 5). A different binding strength of annexins V and I in
the presence of Ca 2+ to PL vesicles … on ion-induced aggregation and fusion of PS vesicles is …

… This lipid is enriched at sites of initial mineralization in these tissues, especially where
matrix vesicles are most abundant. PS also has a ready affinity for Ca 2+ ions which, in the …

… In order to assess the ability of DPPS to stabilize ion complexes composed by Ca 2+ and
phosphate and trigger ACP nucleation, we performed a titration experiment to assess …

… Calcium ion-induced fusion events in suspensions of large unilamellar phosphatidylserine
(PS) … Mixing of vesicle contents was studied by measuring the increase in terbium emission …

… vesicles at 0.15 M ionic strength as a function of calcium … V with vesicles containing 20% PS
at physiological ionic strength … The binding constant becomes weaker as the ionic strength is …

… concentrations of ions; vesicle surface … of phosphatidylserine vesicles as a function of Ca
2+ concentration in the subphase. The surface tension did not change appreciably until the Ca 2…

We have measured the temperature dependence calcium-induced fusion of sonicated
phosphatidylserine vesicles. The vesicles were incubated in the presence of calcium at a …

… association of Ca 2+ and Mg 2÷, both separately and together, with phosphatidylserine
vesicles. We … Phosphatidylserine was isolated from beef brain as previously described [ 1, 4, 5 ]. …

… While the Ca2+-induced fusion of phosphatidylserine (PS)1 vesicles has been studied
extensively and theinteraction of Ca2+ with PS vesicles is well understood (Portis et al., 1979; Wil…
