Spin resonance spectroscopy with an electron microscope [PDF]

Quantum Science and Technology
Abstract Coherent spin resonance methods, such as nuclear magnetic resonance and electron spin resonance spectroscopy, have led to spectrally highly sensitive, non-invasive quantum imaging techniques. Here, we propose a pump-probe spin resonance spectroscopy approach, designed for electron microscopy, based on microwave pump fields and ...

Base-specific spin-labeling of RNA for structure determination [PDF]

, 2007
To facilitate the measurement of intramolecular distances in solvated RNA systems, a combination of spin-labeling, electron paramagnetic resonance (EPR), and molecular dynamics (MD) simulation is presented. The fairly rigid spin label 2,2,5,5-tetramethyl-

Protein-induced changes in DNA structure and dynamics observed with noncovalent site-directed spin-labeling and PELDOR [PDF]

, 2012
Site-directed spin labeling and pulsed electron–electron double resonance (PELDOR or DEER) have previously been applied successfully to study the structure and dynamics of nucleic acids. Spin labeling nucleic acids at specific sites requires the covalent

Spin labelling via metabolic glycoengineering for studying post-translational protein modification by electron paramagnetic resonance spectroscopy [PDF]

, 2023
Post-translational modifications are involved in many cellular processes. The addition of O-linked β-N-acetylglucosamine (O-GlcNAc) is a ubiquitous post-translational modification essential for regulatory processes in mammalian cells.
