  • 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

  • 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

  • Bradford Assay Performed on BMG LABTECH´s FLUOstar Omega with new Evaluation Software

    Determining the protein concentration of samples is a necessary and often used method in biochemistry. Different colorimetric protein assays have been developed. The most commonly used methods are the Bradford assay, the Lowry assay and the BCA assay. In this application note we demonstrate how to determine the protein concentration of samples by using the Bradford assay and the new FLUOstar Omega. more

  • Do you see the complete picture?

    Gel permeation chromatography (GPC) or also named size exclusion chromatography (SEC) is the most often used method for determining the molecular weight of natural and synthetic macromolecules. One specific strength of this method lies in the fact that by the separation process the whole molecular weight distribution is obtained. The molecular weight distribution contains much larger information for the characterization of polymer samples compared to a single value. more
