ONE common difficulty with automated gel and blot imaging systems is that of photographic resolution. Images are typically displayed on monitors at a standard resolution of 72 dot per inch (dpi). When it comes to printing and publication, this is…
MANY biological samples are prone to photo degradation, where the action of light causes changes that can invalidate subsequent laboratory tests. Micronic says that its Amber polypropylene storage tubes ensure the integrity of light sensitive biological samples, even over long-term…
THE Eclipse Ts2R is Nikon’s new intermediate-sized inverted research microscope, an instrument which can be configured for a number of observation methods including phase contrast, emboss contrast, Hoffman modulation contrast, and differential interference contrast (DIC). Now Prior Scientific has introduced…
THE RECORD for continuous power output from a terahertz quantum cascade laser has been almost doubled to 230 milliWatts, researchers in China have reported. Terahertz wavelengths remain a relatively low-power part of the electromagnetic spectrum, lying between infrared and microwave.…
A NOVEL pocket-sized DNA sequencer of the type used on the International Space Station can also be used to preselect DNA strands for sequencing – greatly reducing biological sample analysis time. Researchers at the University of Nottingham UK, developed the…
ZIKA virus is presently causing significant worldwide concern due its rapid spread across the globe and suggested connection to a neurological birth disorder. The outbreak began in Brazil in 2015 and has since spread throughout South and Central America, and…
NITROGEN blowdown evaporation has been adopted by many labs for the removal of chromatography solvents such as acetonitrile, dichloromethane, hexane, and methanol. The latest blowdown evaporator from Porvair Sciences, the Ultravap Levante, is equipped with an RS232 connection and a…
CRISPR/Cas gene editing is a relatively new technique which offers high accuracy in gene targeting and better target sequence selection, with less complexity and less off-target toxicity than previous genome editing technologies. Amsbio provides a standalone premade Cas9 expression lentivirus,…
RAMAN spectroscopy is being used to monitor biochemical changes and inter-donor variability in stored red blood cell (RBC) units, without the need to open the bags and remove samples. Research into the technique has recently been published in the journal…
A NOVEL type of underwater microscope promises to overcome the difficulties of studying small organisms in the laboratory, by making it possible to view them in their natural habitat. Many biological processes in the oceanic world take place at millimetre…
