  2. 16. Isolation of caveolae using affinity two-phase partitioning

    Author : Parisa Abedinpour; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metabolism; Biokemi; Metabolism; Biochemistry; basolateral; apical; immunoaffinity; wheat germ agglutinin; caveolin; caveolae caveolae enriched fraction; plasma membranes; rat lung; rat liver; Affinity Partitioning; two-phase partitioning;

    Abstract : The intention of this work was to establish alternative purification methods to obtain highly purified caveolae from various tissues. In order to isolate caveolae, sufficiently pure plasma membranes are needed. READ MORE

  4. 17. Supported Lipid Membranes and Their Use for the Characterization of Biological Nanoparticles

    Author : Silver Jõemetsa; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fluorescence microscopy; supported lipid bilayer; lipophilic dyes; size determination; diffusion; microfluidics;

    Abstract : Biological nanoparticles (BNPs) are nano-sized lipid vesicles of biological origin, which are involved in multiple biological processes. BNP characterization techniques are critical for improving the understanding of how these particles contribute to cellular communication, viral infections and drug-delivery applications. READ MORE

  5. 18. Intramembranous arrangement of phospholipids and dolichol in microsomal and model membranes

    Author : Conny Valtersson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The transfer of phospholipids from the endoplasmic reticulum to the inner mitochondrial membrane was investigated by pulse labeling in vivo. With [3H]gIycerol microsomal phosphatidylethanoiamine and phosphatidylcholine were rapidly labeled during the first 30 min; while maximum incorporation into the inner mitochondrial membrane occured only after about 5 hours.

  6. 19. Molecular Dynamics Simulations of Fluid Lipid Membranes

    Author : Erik G. Brandt; Olle Edholm; Mats Wallin; Markus Deserno; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biological fluid dynamics; biomembranes; hydrodynamics; lipid bilayers; molecular dynamics; neutron spin echo;

    Abstract : Lipid molecules form thin biological membranes that envelop all living cells, and behave as two-dimensional liquid sheets immersed in bulk water. The interactions of such biomembranes with their environment lay the foundation of a plethora of biological processes rooted in the mesoscopic domain - length scales of 1-1000 nm and time scales of 1-1000 ns.
