Cryo-EM and Solid State NMR Together Provide a More Comprehensive Structural Investigation of Protein Fibrils.

The use of multiple techniques to structurally characterize proteins provides models that accurately describe molecular conformations better than a technique used in isolation. Combination approaches allow for the study of proteins not only as rigid objects, but rather dynamic molecules that "breathe" over time. Cryogenic electron microscopy and solid state nuclear magnetic resonance are used jointly to provide a more detailed model of the same protein fibrils, and each technique provides novel insights.
