Electron microscopy has emerged as an important tool for determining the three-dimensional (3D) structures of cellular components. Advances in instrumentation, methods for data collection and techniques for computation are improving the resolution and breadth of application for this powerful technology. Laura Bonetta reports.
A substantial bottleneck in working with proteins, both native and recombinant, is purifying the protein of interest efficiently, with a minimum of labor and cost. Recent advances in purification technology from many companies are making the protein scientist's job easier. Caitlin Smith reports.
