As a versatile tool in structural biology, single particle electron cryo-microscopy (cryo-EM) has been used to determine the three-dimensional (3D) structures of proteins and macromolecular complexes without the need for crystals. Recent technological breakthroughs in electron detector technologies have enabled developments of novel techniques in both data acquisition and image processing. Together, these novel technologies revolutionized single particle cryo-EM and enabled near atomic resolution structure determinations of a broad range of proteins complexes without the need of crystals. It is now feasible to use single particle cryo-EM to determine structures of protein complexes that are challenging for the more traditional X-ray crystallographic structure determination approach. This is particularly true for integral membrane proteins.
