    "abstract": "The small-angle X-ray and neutron scattering, time resolved X-ray small-angle\nand wide-angle diffraction coupled with differential scanning calorimetry have\nbeen applied to the investigation of unilamellar and multilamellar\ndimyristoylphosphatidylcholine (DMPC) vesicles in sucrose buffers with sucrose\nconcentrations from 0 to 60%. Sucrose buffer decreased vesicle size and\npolydispersity and increased an X-ray contrast between phospholipid membrane\nand bulk solvent sufficiently. No influence of sucrose on the membrane\nthickness or mutual packing of hydrocarbon chains has been detected. The region\nof sucrose concentrations 30%-40% created the best experimental conditions for\nX-ray small-angle experiments with phospholipid vesicles.",
