Pulse electron paramagnetic resonance measurements of long-range (nm scale) distances between spin labels site-specifically attached to biomacromolecules have proven highly effective in structural studies. The most commonly used spin labels are stable nitroxide radicals, and measurements are usually carried out at X-band frequencies (∼9.5 GHz, 0.35 T). Higher magnetic fields open new possibilities for distance measurements with increased sensitivity using alternative spin labels containing...[Show more]
