• Dynamic Light Scattering - an Important Tool for Protein Crystallography and Nanotechnology
  

  Dynamic Light Scattering (DLS) is an established technique in the field of protein crystallography. DLS is used to measure hydrodynamic sizes, polydispersities and aggregation effects of protein samples. These are important parameters for the crystallisation of proteins. DLS is also used in the nanotechnology research for the accurate and fast size measurement of nanoparticles made of different materials. more

• Field-Flow Fractionation - The Universal Separation Principle for Particle and Macromolecule Characterization
  

  High molecular weight polymers, bio molecules or particles in a range of a few nanometers up to several microns are more and more important in science and technology. Many applications are based on the specific properties of these materials. For this reason, an exact knowledge of the molar mass or particle sizes distribution is essential for later application as well as for optimization of the production processes or quality control. In addition the knowledge about the chain structure of macromolecules or biopolymers as well as about the shape of particles is often necessary. For this reason those samples, which often can be very complex systems, have to be separated according to parameters such as e.g. hydrodynamic volume or molecular weight. After the separation process the resulting narrow dispersed fractions are detected with different techniques. more

• Blue Light-Induced Conformational Changes in a Light-Regulated Transcription Factor, Aureochrome-1

  Aureochrome-1 (AUREO1) is a blue light (BL) receptor that mediates the branching response in the stramenopile alga, Vaucheria frigida. AUREO1 harbors a basic leucine zipper (bZIP) domain at the N-terminus and a light–oxygen–voltage-sensing (LOV) domain within the C-terminal region, and has been sug more

• Pressure assisted stabilization of biocatalysts at elevated temperatures: Characterization by dynamic light scattering

  Abstract The effect of pressure, at elevated temperatures, is reported on the activity and stability of a thermophilic endo‐ß‐Glucanase from the filamentous fungus Talaromyces emersonii. The production of reduced sugars after treatment at different temperatures and pressures is used as a measure more

• Self-Assembled pH-Sensitive Cholesteryl Pullulan Nanogel As a Protein Delivery Vehicle

  A self-assembled nanogel, derived from an acid-labile cholesteryl-modified pullulan (acL-CHP), was prepared by grafting vinyl ether-cholesterol substituents onto a 100 kD pullulan main chain polymer backbone. Stable nanogels are formed by acL-CHP self-assemblies at neutral pH. The hydrodynamic radiu more
