Syngene, a world-leading manufacturer of image analysis solutions, has announced its G:BOX Chemi XX6 multi-application imager is being utilized by scientists at the University of Brescia for analyzing nitrated proteins. This is providing the researchers with accurate information on changes in proteins and may help to identify biomarkers related to Alzheimer’s disease.

Researchers in the Department of Molecular and Translational Medicine (DMMT) at the University of Brescia in Italy are using a G:BOX Chemi XX6 system to analyze nitrated proteins fluorescently stained with Cy2, Cy3 and Cy5 on 2D DIGE (Difference Gel Electrophoresis) gels. These proteins have been isolated from the blood of healthy individuals, as well as Alzheimer’s sufferers and studying them is allowing scientists at the university to accurately detect which proteins are being nitrated. This information is then being used to identify biomarkers associated with disease onset and could contribute in future to selecting people at risk of developing the disease for therapeutic and other interventions.

Dr Daniela Uberti, Assistant Professor of Pharmacology in the DMMT at the University of Brescia explained: “We have been sampling blood from healthy volunteers and Alzheimer’s disease patients for around 15 years but the amount of nitrated proteins we’re looking for, to indicate disease onset, is very small so we need to use a DIGE approach to find them. This means we have to have sensitive detection with an imager that can visualize nanogram amounts of protein.”

Daniela added: “We tested the G:BOX Chemi XX6 with our large 2D DIGE gels and found the system could easily detect nitrated proteins at below the nanogram level and is why we acquired the technology. Since then many researchers in our department have said the system is easy to use so we are very satisfied with the performance of the G:BOX XX6 in our laboratory.”

“We’re delighted to hear that the G:BOX Chemi XX6 multi-functional imager is helping with finding vital biomarkers for Alzheimer’s disease,” states Rob Van den Broek, European Sales Manager at Syngene, “the work at the University of Brescia demonstrates that for accurate, sensitive proteomics research the G:BOX Chemi XX6 imaging system is an excellent choice.”

Syngene

G:BOX Chemi XX6 gel imaging system has a high resolution camera for imaging multiple sample types and sizes, from fluorescence 1D to 2D gels to chemiluminescent blots. Your lab’s imaging system shouldn’t control how you detect proteins on Western blots. Chemiluminescence is great if you want sensitive detection of picogram or femtogram amounts, while fluorescence lets you quantify and detect multiple different proteins on one blot.

Protein PurificationProtein purification is a vital step in drug discovery, therapeutics, biotech and life science research. The purification process typically involves subcellular or membrane protein extraction with cell lysis kits, separation of proteins from cell debris by filtration or spin columns, and the isolation of proteins of interest from other proteins and impurities with affinity purification (including fusion protein tags and antibody binding proteins A, G and L), immunoprecipitation or chromatographic methods, such as ion exchange, size exclusion and immobilized metal affinity chromatography. All purification methods come in multiple formats for your laboratory needs, including agarose or magnetic beads, resins, columns and filter plates.

The use of biomarkers in research and diagnosis can indicate a normal or disease state or drug response of cells / tissues. Biomarkers include genetic markers, cell surface markers such as antigens, antibodies or receptors and secreted molecules such as cytokines. An assay system is required for identification of biomarkers. :Clinical ChemistryBiochemistry (or clinical chemistry) involves the analysis of bodily fluids using chemical tests. Techniques used include HPLC, chromatography, spectroscopy, mass spectrometry, immunochemical, electrophoresis, turbidometric / spectrophotometric assay, MRI and ISE analysis. Tests are often carried out on plasma or serum but urine (urinalysis) and fecal specimens are also processed.FluorescenceThe emission of fluorescence occurs when a photon of energy is supplied to a fluorescent chemical compound by an external source, causing it to become excited. Fluorescence can be detected and measured for different purposes using microplate readers, fluorescence microscopes, fluorescence scanners, and flow cytometers.ImagingImaging techniques are essential for obtaining visual representations of samples to understand structures, processes, and function in biological, chemical, and physical research. These tools range from traditional light microscopy to advanced imaging modalities like MRI and electron microscopy, providing researchers with valuable data for diagnostics, drug discovery, and material analysis.
