  • Luminous bacterial proteins detect chemicals in water

    While residual medications don’t belong in the water, trace metals from industrial process waters handled by the recycling industry are, in contrast, valuable resources. Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have developed a simple color sensor principle which facilitates the more

  • Decomposition of textile products in the ground

    Like all organic materials, textiles will decompose under the influence of water and microorganisms in the ground. Under comparable environmental conditions, it depends mainly on the raw materials used whether the decomposition process takes place over the course of months, years, decades or even ce more

  • Cost-effective Determination of Inorganic Anions and Cations in Municipal Drinking Water

    Thermo Fisher Scientific Inc. announced a new application demonstrating the separation of common inorganic anions and cations in municipal drinking water samples on the capillary Thermo Scientific Dionex IonPac AS19 hydroxide-selective anion-exchange column and the Thermo Scientific Dionex IonPac CS 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

  • 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

  • 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
