Lipoplex size is a major determinant of in vitro lipofection efficiency
The inhibition effect of serum on the transfection efficiency of cationic liposome–DNA complexes (lipoplexes) is a major obstacle to the application of this gene delivery vector both in vitro and inExpand
Grafted poly-(ethylene glycol) on lipid surfaces inhibits protein adsorption and cell adhesion.
Monolayers of dipalmitoyl-phosphatidylethanolamine (DPPE) mixing with various mole percentages of distearoyl-phosphatidylethanolamine (DSPE)-conjugated poly-(ethylene glycol) (PEG m.w. 750-5000) wereExpand

C3H/10T1/2 mouse embryo fibroblasts were stimulated by a steady electric field ranging up to 10 V/cm. Some cells elongated and aligned perpendicular to the field direction. A preferential positionalExpand
Direct Measurement of Polyethylene Glycol Induced Depletion Attraction between Lipid Bilayers
Although polyethylene glycol (PEG) is widely used for aggregating or fusing cells, the forces responsible for these interactions have remained elusive. Through a variety of techniques includingExpand
Cytoplasmic regulation of tight-junction permeability: effect of plant cytokinins.
The significance of the "leaky" tight junction might be understood better if cells of the epithelial monolayer possessed mechanisms to regulate molecular flow through the junction. To test thisExpand
Physicochemical characterization and purification of cationic lipoplexes.
Cationic lipid-nucleic acid complexes (lipoplexes) consisting of dioleoyltrimethylammoniumpropane (DOTAP) liposomes and plasmid DNA were prepared at various charge ratios (cationic group toExpand
Amphipathic helix and its relationship to the interaction of calcitonin with phospholipids.
Salmon, porcine, and human calcitonins interact with phosphatidylglycerol to form water-soluble complexes, but these peptides do not interact with the zwitterionic lipids phosphatidylcholine orExpand
The structure and stability of phospholipid bilayers by atomic force microscopy.
Atomic force microscopy (AFM) was used to investigate the structure, stability, and defects of the hydrophilic surfaces of Langmuir-Blodgett bilayer films of distearoylphosphatidylcholine (DSPC) andExpand
Dehydration-induced lamellar-to-hexagonal-II phase transitions in DOPE/DOPC mixtures.
Plasma membranes of protoplasts isolated from non-acclimated rye plants undergo a transition from the bilayer to the inverted hexagonal (HII) phase during freeze-induced dehydration at -10 degrees C.Expand
Studies of cell pellets: II. Osmotic properties, electroporation, and related phenomena: membrane interactions.
Using the relations between pellet structure and electric properties derived from the preceding paper, the responses of rabbit erythrocyte pellets to osmotic or colloidal-osmotic effects fromExpand
