![]() We also offer unique instruments for electrophoretic light scattering (MP-PALS), differential refractometry and differential viscosity. The plasmid DNA-histone interaction leads to well-defined mono-disperse chromatin-like complexes their formation, composition and solution properties have been studied by laser light scattering and related physico-chemical methods. Our dynamic light scattering (DLS) products operate in traditional cuvette as well as on-line and automated, high-throughput modes. Dynamic light scattering (DLS) studies the properties of inhomogeneous and. Chromatin can be reconstituted by interaction of DNA under well chosen experimental conditions with a selected group of histones, basic proteins of the nucleoprotein complex in the chromosome. Sizeexclusion columns and on-line light scattering detectors are the key. Structural transitions can be studied in a variety of solvents and folding properties of DNA investigated. The diffusion coefficient, and hence the hydrodynamic radii calculated from it, depends on the size and shape of macromolecules. ![]() ![]() The recently discovered plasmid DNA molecules are excellent objects of study, being monodisperse, in a convenient molecular mass range, and obtainable in supercoiled, relaxed circular and open linear conformations. in quantitative fluorescence nano-imaging & single molecule dynamics. Dynamic light scattering (DLS), also known as photon correlation spectroscopy (PCS), is a very powerful tool for studying the diffusion behaviour of macromolecules in solution. Photon correlation and light beating spectroscopy, using laser radiation, allows the measurement of dynamic properties such as diffusion coefficients and, perhaps, the characterization of internal motion. Thirteen key questions to ask when buying a Multi-Angle Light Scattering (MALS) or Dynamic Light Scattering (DLS) instrument. Download Citation Dynamic Light Scattering Dynamic light scattering is commonly used to monitor the diffusion of small particles in either liquids or aerosols and can be used to evaluate. Classical fluctuation and scattering theory has enabled the study of equilibrium properties such as molecular mass, size and intermolecular interactions of synthetic and biological macromolecules.
