DOI: 10.1002/open.201900119

Abstract: Abstract The availability of bioresistant spin labels is crucial for the optimization of site‐directed spin labeling protocols for EPR structural studies of biomolecules in a cellular context. As labeling can affect proteins’ fold and/or function,… read more here.

DOI: 10.1039/d0cc03101a

Abstract: Photoexcited triplet states are gaining popularity as spin labels in pulsed electron paramagnetic resonance (EPR) spectroscopy. Here, we demonstrate that the fluorophores Eosin Y, Rose Bengal and Atto Thio12 are suitable markers for distance determination… read more here.

DOI: 10.1098/rsos.180166

Abstract: Deposition of amyloid fibrils is a pathological hallmark of Alzheimer's disease. Aβ42 is the major protein whose aggregation leads to the formation of these fibrils. Understanding the detailed structure of Aβ42 fibrils is of particular… read more here.

DOI: 10.3390/membranes12100962

Abstract: The spin-lattice relaxation rate (T1−1) of lipid spin labels obtained from saturation recovery EPR measurements in deoxygenated membranes depends primarily on the rate of the rotational diffusion of the nitroxide moiety within the lipid bilayer.… read more here.
