AMRESCO´s Fluorescent DNA Quantitation Kit quantifies double-stranded DNA in the low nanogram up to 5 microgram per ml range using fluorescent bisBenzimide H33258 (Hoechst) dye. Solon, Ohio (PRWEB) May 06, 2013 DNA quantitation is crucial to experimental design and interpretation of results, especially in sensitive molecular biology applications such as PCR, or for any comparative analysis of multi-source DNA samples. Although UV spectrophotometric measurement at 260 nm is the most...

Researchers at the University of California, San Diego School of Medicine have created a new generation of fast-acting fluorescent dyes that optically highlight electrical activity in neuronal membranes. The work is published in this week's online Early Edition of the Proceedings of the National Academy of Sciences. The ability to visualize these small, fast-changing voltage differences between the interior and exterior of neurons — known as transmembrane potential — is...

In work published in the June 2011 issue of Experimental Biology and Medicine, Kolossov, Spring and their co-investigators - a multidisciplinary team within the Institute for Genomic Biology at the University of Illinois - have transferred the concept of redox-sensitive Green Fluorescent Proteins (GFPs) to a quantitative Förster resonance energy transfer (FRET) imaging platform. For the FRET-based sensors, a change in redox induces a conformational change in a redox-sensitive switch that...

AMRESCO expands its popular EZ-Vision line with dyes and stains that are environmentally sensitive, are non-toxic, non-mutagenic and eliminate the use of hazardous ethidium bromide. In addition to being PEOPLE-PLANET-SAFE, the EZ-Vision line offers increased visualization, efficiency and consistency at the bench. Cleveland, Ohio (PRWEB) May 18, 2011 With life science researchers calling for products that are safer for use in the lab and the environment, AMRESCO's EZ-Vision® In-Gel...

Proteins are the most important functional biomolecules in nature with numerous applications in life science research, biotechnology and medicine. So how can they be modified in the most effective way to attain certain desired properties? In the past, the modifications were usually carried out either chemically or via genetic engineering. The team of Professor Arne Skerra from the TUM Chair of Biological Chemistry has now developed a more elegant combined solution: By extending the otherwise...

Development Will Open New Avenues for Research Researchers from Carnegie Mellon University's Molecular Biosensor and Imaging Center (MBIC) are turning up the brightness on a group of fluorescent probes called fluoromodules that are used to monitor biological activities of individual proteins in real-time. This latest advance enhances their fluormodule technology by causing it to glow an order of magnitude brighter than typical fluorescent proteins. The new fluoromodules are five- to...

Scientists in Southampton, UK, and Ulm and Karlsruhe in Germany have shown that a variant form of a fluorescent protein (FP) originally isolated from a reef coral has excellent properties as a marker protein for super-resolution microscopy in live cells. Their findings have been published online by Nature Methods and will appear in print in the upcoming August issue of that journal. Fluorescent proteins produced by a range of marine animals glow with a rainbow of colors, adding to the visual...

Scientists at Carnegie Mellon University's Department of Chemistry and Molecular Biosensor and Imaging Center (MBIC) are advancing the state-of-the-art in live cell fluorescent imaging by developing a new class of fluorescent probes that span the spectrum "” from violet to the near-infrared. The new technology, called fluoromodules, can be used to monitor biological activities of individual proteins in living cells in real time. At the 239th national meeting of the American Chemical...

If you wanted to know if your child had a fever or be certain that the roast in the oven was thoroughly cooked, you would, of course, use a thermometer that you trusted to give accurate readings at any temperature within its range. However, it isn't that simple for researchers who need to measure temperatures in microfluidic systems"”tiny, channel-lined devices used in medical diagnostics, DNA forensics and "lab-on-a-chip" chemical analyzers"”as their current "thermometer" can...

Einstein research helps scientists see cancer and other cells at the molecular level Remarkable new tools that spotlight individual cellular molecules are transforming biomedical research. Scientists at the Gruss Lipper Biophotonics Center at the Albert Einstein College of Medicine of Yeshiva University have spearheaded their use in a series of papers, including one published Sunday in the online version of Nature Methods. These new tools are photoactivatable fluorescent proteins (PAFPs) and...
