  4. 4. Groove-binding Unsymmetrical Cyanine Dyes for DNA Applications

    Author : Maja Eriksson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polarized spectroscopy; bacteriophage T5; cryo-transmission electron microscopy; dynamic light scattering; DNA; intercalation; cyanine dyes; groove-binding; fluorescence spectroscopy; gel electrophoresis;

    Abstract : This work focuses on interactions between DNA and a group of newly developed unsymmetrical cyanine dyes. The aim of the work was to discover fluorescent dyes that can be used in biophysical studies of natural DNA where minimum perturbation of the DNA-helix is essential, where a slow dissociation rate of the dyes is needed and where the ionic strength is an important parameter.

  5. 5. Membrane Orientation Studies with Polarized Light Spectroscopy

    Author : Malin Ardhammar; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lipid vesicle; membrane orientation; flow linear dichroism; oriented circular dichroism;

    Abstract : Lipid vesicles are versatile tools in modern biophysical science. They can be used as models of the cell membrane, to examine permeability, stability and behavior of molecules in the bilayer. They may act as transporters in a pharmacological context, designed to deliver their cargo to a certain place in the patient. READ MORE
