Magic angle spinning NMR of proteins: high-frequency dynamic nuclear polarization and (1)H detection.

abstract：:Peptides and proteins have been found to possess an inherent tendency to convert from their native functional states into intractable amyloid aggregates. This phenomenon is associated with a range of increasingly common human disorders, including Alzheimer and Parkinson diseases, type II diabetes, and a number of syst...
