Protein expression systems are very widely used in the life sciences, biotechnology and medicine. Traditional strategies for recombinant protein expression involve the transformation of a gene expression vector into prokaryotic expression hosts and culturing the cells so that they express the desired protein. Using an inducible expression cassette the onset of the protein expression can be controlled by several inducer (f.e. chemical, temperature, cold).<br><br><strong>Technology</strong><br> We offer two compact plasmids for facile light regulated expression of target proteins in prokaryotic hosts. Dependent from the application, one plasmid can be used for light activated and one for light inactivated gene expression. Both plasmids are working without exogenous addition of chromophores or expensive chemical inducers and allow a specific, spatially- and temporally precise control of protein expression. A competitive advantage is the use of light as inducer especially for the production of recombinant proteins. Another advantage is the very precise control of protein expression which is very relevant for several research applications. By using standard chemical inducers a spatially and temporally precise control of protein expression is not possible.<br> <strong><br><br> <b>Benefits:</b> <ul>

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, provider of research and development services for OLED lighting solutions, announces the founding of the “OLED Licht Forum” and presents latest OLED design and lighting solutions during light+building, from March 18th – 23rd, 2018 in Frankfurt a.M./Germany, at booth no. F91 in Hall 4.0.
They are united in their passion for OLED (organic light emitting diodes) lighting with all of its unique facets and application possibilities. Thus experts in...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
