Spin Labeling of Surface Cysteines Using a Bromoacrylaldehyde Spin Label. [PDF]
Appl Magn Reson, 2021 AbstractStructural investigations of proteins and their biological complexes are now frequently complemented by distance constraints between spin labeled cysteines generated using double electron–electron resonance (DEER) spectroscopy, via site directed spin labeling (SDSL).

Erythrosin B as a New Photoswitchable Spin Label for Light-Induced Pulsed EPR Dipolar Spectroscopy [PDF]
Molecules, 2022 We present a new photoswitchable spin label for light-induced pulsed electron paramagnetic resonance dipolar spectroscopy (LiPDS), the photoexcited triplet state of erythrosin B (EB), which is ideal for biological applications.

Rigid and stable nitroxide spin label for high-resolution distance measurements on proteins by DEER experiments [PDF]
Magnetic Resonance LettersThe distance distributions between two site-specifically anchored spin labels in a protein, measured by pulsed electron-electron double resonance (PELDOR or DEER), provide rich sources of structural and conformational restraints on the proteins or their ...

RosettaEPR: rotamer library for spin label structure and dynamics. [PDF]
PLoS ONE, 2013 An increasingly used parameter in structural biology is the measurement of distances between spin labels bound to a protein. One limitation to these measurements is the unknown position of the spin label relative to the protein backbone. To overcome this

Exploring the Interactions of Ruthenium (II) Carbosilane Metallodendrimers and Precursors with Model Cell Membranes through a Dual Spin-Label Spin-Probe Technique Using EPR [PDF]
Biomolecules, 2019 Dendrimers exhibit unique interactions with cell membranes, arising from their nanometric size and high surface area. To a great extent, these interactions define their biological activity and can be reported in situ by spin-labelling techniques.

Resting state BOLD-perfusion coupling patterns using multiband multi-echo pseudo-continuous arterial spin label imaging [PDF]
Scientific ReportsThe alteration of neurovascular coupling (NVC), where acute localized blood flow increases following neural activity, plays a key role in several neurovascular processes including aging and neurodegeneration.

Membranes, 2022 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.
