  • Researchers use functional MRI to study small-scale strokes

    Two Cornell researchers -- one in Manhattan and the other in Ithaca -- aim to develop the first noninvasive functional MRI imaging technique for studying small-scale strokes in mice, which could eventually be used for clinical research in humans. The research is supported by a Samuel C. and Nancy M more

  • Microchip patented which separates and extracts tumor cells in the blood

    Ikerlan-IK4 and Mondragón Unibertsitatea are taking part in a project initiated by the Spanish National Research Council, CSIC, and which has developed a microchip capable of separating and extracting tumour cells in the blood stream by means of ultrasonic waves. The Foundation General Hospital of t more

  • Advanced imaging for bone research and materials science

    A novel nano-tomography method developed by a team of researchers from the Technische Universität München (TUM), the Paul Scherrer Institute (PSI) and the ETH Zurich opens the door to computed tomography examinations of minute structures at nanometer resolutions. The new method makes possible, for e more

  • 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

  • Fugene® HD Transfection Reagent: Superior Performance for Challenging Expression Studies

    The ability to efficiently introduce foreign molecules into cells constitutes an important tool in any laboratory and facilitates studies of gene regulation and protein function. A plethora of transfection methods have been developed for transfer of DNA into mammalian and animal cells. Those methods either utilize the physicochemical properties of the vector-carrier of the DNA or use mammalian viruses. In the first group of methods, some classic techniques are well-known, such as: calcium phosphate, DEAE-dextran, electroporation liposome-mediated delivery, direct microinjection/biolistic particle delivery, and non-liposomal multi-component reagents. Viral vector systems use both DNA (Adeno-) and RNA (Retro-, Lenti-) viruses. more
