• Clicking Tc-99m SPECT Probes Together

  Radioactively labeled compounds are important for use as imaging probes or radiotherapeutic agents. Most radioisotopes with suitable decay properties are transition metals or elements with metallic character. Therefore, bifunctional chelators are required for stable tethering of a given radionuclide more

• MorphoSys Announces Acquisition of Sloning

  MorphoSys AG announced the acquisition of Sloning BioTechnology GmbH. The transaction will make MorphoSys the sole source of Sloning's state-of-the-art Slonomics technology, which improves the assembly and quality of protein libraries. By integrating Slonomics into its existing antibody technology p more

• Water is an active element in proteins
  

  Biophysicists in Bochum have discovered a diode for protons: just like the electronic component determines the direction of flow of electric current, the “proton diode” ensures that protons can only pass through a cell membrane in one direction. Water molecules play an important role here as active 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

• Enabling Cancer Research with FuGENE® HD Transfection Reagent
  

  A major problem in some areas of cancer research is the difficulty of transfecting a significant number of the cells of interest, while minimizing the cytotoxic or other off-target effects of the transfection event itself. It is well-known that the use of some transfection reagents results in high levels of expression of the gene of interest in surviving cells, but also in high levels of cell death or other cellular alterations. FuGENE® HD Transfection Reagent overcomes these problems, results in high ­levels of transfection in many cancer cell lines, and thus enables researchers to conduct experiments that have previously not been possible. more

• Epitope Mapping Using the In Vitro Rapid Translation System RTS 100
  

  The Rapid Translation System (RTS) represents a cell-free system that allows efficient production of protein from linear DNA sequences. This article gives a brief outline of the use of the RTS technology in linear epitope mapping and shows its promise for reducing time-consuming cloning and cell-lysis steps. more
