Technical progress in solid-state NMR spectroscopy under magic angle spinning (MAS) has enabled significant improvement in sensitivity and resolution over the past few years. This methodology is essential for high-resolution studies on samples that are only available in sub-milligram amounts and cannot be obtained in deuterated form. Examples of such systems are proteins that cannot be expressed in eukaryotic systems or membrane proteins which cannot be refolded. Proton-detected experiments on such samples only reach the necessary resolution if MAS rates in the range above 100 kHz can be reached. These techniques were established in the past 3-4 years and only very recently have NMR probes become commercially available that enable such experiments. The possibility to conduct experiments on such equipment opens up completely new perspectives to research groups at BNMRZ addressing biological questions with solid-state MAS NMR.

在过去的几年里，魔角旋转（MAS）下的固态NMR光谱技术的进步使灵敏度和分辨率得到了显着提高。这种方法对于高分辨率研究只有亚毫克数量的样品而不能以氘代形式获得的样品至关重要。此类系统的实例是不能在真核系统中表达的蛋白质或不能重折叠的膜蛋白。只有当MAS速率达到100 kHz以上时，对这些样品的质子检测实验才能达到必要的分辨率。这些技术是在过去的3-4年中建立的，直到最近才有NMR探针商业化，使这样的实验成为可能。在这种设备上进行实验的可能性为BNMRZ的研究小组开辟了全新的视角，用固态MAS NMR解决生物学问题。
