1. 1. Oscillatory phenomena in chloroplasts from spinach cotyledons

   Författare :Gertrud Puu; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : A suspensionofchloroplasts, isolated from spinach cotyledons, was found to be an oscillatory system, i.e. a system in which one parameter (or more) varies over time in a fairly regular way.The oscillations, with a period of fifteen to twenty minutes,occured spontaneously in the light as well as in the dark and were self-sustained for several hours.

3. 2. Phospholipid membranes in biosensor applications : Stability, activity and kinetics of reconstituted proteins and glycolipids in supported membranes

   Författare :Inga Gustafson; Gertrud Puu; Sven Lindskog; Peter Konradsson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Phospholipid films; Liposomes; Membrane proteins; Glycolipids; Ellipsometry; Langmuir Blodgett LB ; Surface plasmon resonance SPR ; Resonant mirror RM ; Atomic force microscopy AFM ; Biosensors; Biokemi; Biochemistry; Biokemi; Biochemistry; biokemi;

   Sammanfattning : In this study the formation of supported membranes onto planar solid supports has been investigated. The stability and activity of reconstituted membrane receptors has been studied. The potential use of such preparations in biosensor applications is discussed.The lipid films were made by the Langmuir Blodgett and by the liposome fusion techniques. LÄS MER
