Crystal clear: Preparing solid-state NMR samples that yield high-resolution spectra displaying high sensitivity is time-consuming and complicated. A sample of the 59 kDa protein DnaB, prepared simply by preparative centrifugation, provides spectra that are as good as the ones from carefully grown microcrystals.
