Folding proteins in a cell

Facebook X LinkedIn Email
When it comes to protein folding, cells have a few tricks up their sleeve, report researchers from the University of Illinois at Urbana-Champaign. Using laser-based techniques, they have shown for the first time that cells strongly modulate the speed and stability of protein folding. “This provides an entirely new mechanism by which cells can control what their proteins do,” said Martin Gruebele, professor of chemistry, physics and biophysics. “In addition to folding reactions, other reactions are likely also to be modulated in the cell.” Gruebele said...Read full article

    fluorescence microscopy
    Fluorescence microscopy is a specialized optical imaging technique used in biology, chemistry, and materials science to visualize and study specimens that exhibit fluorescence. Fluorescence is the phenomenon where a substance absorbs light at one wavelength and emits light at a longer wavelength. In fluorescence microscopy, fluorescent dyes or proteins are used to label specific structures or molecules within a sample. The basic principles of fluorescence microscopy involve illuminating the...
