Phase Coexistence in Single-Lipid Membranes Induced by Buffering Agents
Recent literature has shown that buffers affect the interaction between lipid bilayers through a mechanism that involves van der Waals forces, electrostatics, hydration forces and membrane bending rigidity. This letter shows an additional peculiar effect of buffers on the mixed chain 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) lipid bilayers, namely phase coexistence similar to what...
متن کاملThree-Phase Coexistence in Lipid Membranes.
Phospholipid ternary systems are useful model systems for understanding lipid-lipid interactions and their influence on biological properties such as cell signaling and protein translocation. Despite extensive studies, there are still open questions relating to membrane phase behavior, particularly relating to a proposed state of three-phase coexistence, due to the difficulty in clearly disting...
متن کاملCharge-induced phase separation in lipid membranes.
Phase separation in lipid bilayers that include negatively charged lipids is examined experimentally. We observed phase-separated structures and determined the membrane miscibility temperatures in several binary and ternary lipid mixtures of unsaturated neutral lipid, dioleoylphosphatidylcholine (DOPC), saturated neutral lipid, dipalmitoylphosphatidylcholine (DPPC), unsaturated charged lipid, d...
متن کاملPhase separation in lipid membranes.
Cell membranes show complex behavior, in part because of the large number of different components that interact with each other in different ways. One aspect of this complex behavior is lateral organization of components on a range of spatial scales. We found that lipid-only mixtures can model the range of size scales, from approximately 2 nm up to microns. Furthermore, the size of compositiona...
متن کاملPhase Transitions in Lipid Membranes
The seminar treats phase transitions in lipid membranes, with the focus on the main lipid bilayer phase transition. It reveals the microscopic picture and reviews the key factors leading to the presented phenomena. A general discussion on models is made and some concrete examples are presented in more detail. Finally, experimental approaches to study the phase behavior of lipid membranes are di...
