Angewandte Chemie, 2016 Double electron-electron resonance (DEER) can be used to study the structure of a protein in its native cellular environment. Until now, this has required isolation, in vitro labeling, and reintroduction of the protein back into the cells.

Detection of atomic spin labels in a lipid bilayer using a single-spin nanodiamond probe [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2013 Magnetic field fluctuations arising from fundamental spins are ubiquitous in nanoscale biology, and are a rich source of information about the processes that generate them.

Myocardial arterial spin labeling [PDF]
Journal of Cardiovascular Magnetic Resonance, 2016 Arterial spin labeling (ASL) is a cardiovascular magnetic resonance (CMR) technique for mapping regional myocardial blood flow. It does not require any contrast agents, is compatible with stress testing, and can be performed repeatedly or even continuously. ASL-CMR has been performed with great success in small-animals, but sensitivity to date has been

Structural Refinement of Proteins by Restrained Molecular Dynamics Simulations with Non-interacting Molecular Fragments. [PDF]
PLoS Computational Biology, 2015 The knowledge of multiple conformational states is a prerequisite to understand the function of membrane transport proteins. Unfortunately, the determination of detailed atomic structures for all these functionally important conformational states with ...

Erythrosin B as a New Photoswitchable Spin Label for Light-Induced Pulsed EPR Dipolar Spectroscopy
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.

Selectivity of interaction of spin-labelled lipids with peripheral proteins bound to dimyristoylphosphatidylglycerol bilayers, as determined by ESR spectroscopy. [PDF]
, 1989 The selectivity of interaction between spin-labelled lipids and the peripheral proteins, apocytochrome c, cytochrome c, lysozyme and polylysine has been studied using ESR spectroscopy. Derivatives of phosphatidylcholine (PC), phosphatidylethanolamine (PE)

Spin-label scanning reveals conformational sensitivity of the bound helical interfaces of IA3
AIMS Biophysics, 2018 IA3 is an intrinsically disordered protein (IDP) that becomes helical when bound to yeast proteinase A (YPRA) or in the presence of the secondary stabilizer 2,2,2-trifluoroethanol (TFE).

Polarized Lambdas in the Current Fragmentation Region [PDF]
, 1996 Data on the nucleon spin structure suggests that the $u$ (and $d$) quark distributions in the $\Lambda$ hyperon may be polarized. If this correlation carries over into fragmentation, then the study of polarized $\Lambda$'s in the current fragmentation ...

Spin Probes as Scavengers of Free Radicals in Cells
Applied Sciences, 2022 Spin probes can be used to monitor biological membranes, including the penetration of different molecules into cells. The aim of the present studies was an investigation of the endocytosis process of two spin labels—2,2,6,6-Tetramethylpiperidine-1-oxyl ...
