The UVIchemi chemiluminescence imaging system can be used for imaging western blots which are an important method used to determine the effectiveness of gene transfer. In many cases, the images produced can be analysed (quantified) using UVIband analysis software also from UVItec.
Not that rigorous? Anathema though this thought may be to most pharmaceutical quality managers, it is nonetheless quite apparent to companies such as ours, which make products critical to maintaining quality in pharmaceutical and other applications
Foss has released a new generation of analysers for routine analysis of wine and grape-must. The analysers are: WineScan Grape for dedicated analysis of grape-must, WineScan Flex for analysis of both grape-must and wine and WineScan Auto for efficient, unattended analysis of wine.
Scientists in the US have used the DNA from fish waste to make optical components. The team, led by James Grote of the US Air Force Research Laboratory, says that the material could be used to make optical waveguides, modulators and light-emitting diodes. They also claim that fish DNA, which is abundant and environmentally friendly, could outperform other polymer-based devices.
Penn State University researchers have developed a prototype sonic gas analyser that automatically and continuously tracks the concentration of a gas in an air/gas mixture based on changes in pitch.
Physicists in Switzerland and Germany have made a new type of optical microscope that can produce images without capturing light from the sample. The new device relies on measuring changes in the properties of a gold nanoparticle placed next to the sample. The nanoantenna could have application in sensing devices (Phys Rev Lett 95 200801).
Resonance Health's non-invasive liver diagnostic technology uses magnetic resonance imaging (MRI) technology to provide a scan of the liver which is subsequently analysed to quantify iron loading using FerriScan's proprietary software. It is a novel technology easily applied to anyone with an MRI machine.
The Phenomenex Onyx C18 Semi-Prep 100 x 10 mm is the latest addition to the portfolio of monolithic silica HPLC columns. This format allows for flow rates from 5 to 35 mL/min with loading capacities typically between 10 and 20 mg. Onyx Semi-Prep is suitable for high-throughput purifications where impure samples and abusive ballistic gradients are encountered, such as in combinatorial library purifications. Also, due to the physics of the monolith, the DMSO solvent slug is well mixed, improving purification results. In addition to high-throughput purification advantages Onyx has very low backpressures and good flow characteristics, which allows for injection of very dirty and/or viscous sample.
A Stanford University research team has designed the first microscope sensitive enough to track the real-time motion of a single protein down to the level of its individual atoms
