A new design triples efficiency of cyan fluorescent proteins Scientists have designed a molecule which, in living cells, emits turquoise light three times brighter than possible until recently. This improves the sensitivity of cellular imaging, a technique where biological processes inside a living organism are imaged at high resolution. The results have been published in Nature Communications on 20 March 2012. The lead author of the publication is Antoine Royant from the Institut de...

On March 22, during the 41st Annual Meeting & Exhibition of the American Association for Dental Research (AADR), held in conjunction with the 36th Annual Meeting of the Canadian Association for Dental Research, a symposium titled "Challenges in Salivary Diagnostics" will take place to discuss the issues with saliva collection and storage, proteomic analyses, and the growing interest and availability of commercial tests for salivary biomarkers. Recently there has been a striking...

A new method to reveal the structure of proteins could help researchers understand biological molecules — both those involved in causing disease and those performing critical functions in healthy cells.   For roughly a decade, a technique called solid state nuclear magnetic resonance (NMR) spectroscopy has allowed researchers to detect the arrangements of atoms in proteins that defy study by traditional laboratory tools such as X-ray crystallography. But translating solid state...

A research team led by the University of Melbourne has developed a novel technique that tracks diseased proteins behaving badly by forming clusters in brain diseases such as Huntington´s and Alzheimer´s. The technique published in Nature Methods today is the first of its kind to rapidly identify and track the location of diseased proteins inside cells and could provide insights into improved treatments for brain diseases and others such as cancer.   Developed by Dr Danny...

'Identity check' selectively screens single molecules passing through nanopores A novel type of sensor, based on nanometer-scale pores in a semiconductor membrane, is a step closer to practical use in applications such as analyzing the protein contents of a single cell. Researchers pioneering single-molecule nanopore sensor technology at the Technische Universität München (TUM) have shown its potential through a succession of experiments over the past few...

New method of monitoring protein molecules using gold nanoparticles Scientists at Johannes Gutenberg University Mainz (JGU) in Germany have developed a new method of observing individual proteins. Detailed knowledge of the dynamics of proteins is necessary in order to understand the related biological processes that occur on the molecular level. To date, this information has been obtained by means of labeling proteins with fluorescent substances, but unfortunately this changes the proteins...

A new semi-automated tool called pathwalking makes it possible to generate a "first draft" model of a protein fold taken from near-atomic resolution images of between three and six angstroms (Ã…), said researchers at the National Center for Macromolecular Imaging in the department of biochemistry at Baylor College of Medicine. In a report that appears online in the journal Structure, the BCM team describes the development of the semi-automated protocol that enables researchers...

Using a unique facility in the US, researchers at the University of Gothenburg have found a more effective way of imaging proteins. The next step is to film how proteins work — at molecular level. Mapping the structure of proteins and the work they do in cells could be the key to cures for everything from cancer to malaria. Last year Richard Neutze, professor of biochemistry at the University of Gothenburg, and his research group were among the first in the world to image proteins...
