Extract

Macromolecular microscopy is becoming an increasingly important tool for structural biology. The development of improved capabilities for three-dimensional electron microscopy is critical for optimal progress in emerging integrative research in molecular cell biology. These techniques currently suffer from several severe disadvantages related to the tremendous time and effort required to acquire and analyze the data.

For several years we have been developing software for automated and intelligent acquisition of transmission electron micrographs [1,2,3]. Our overall goal is to develop a system for rapid and routine structure determination of macromolecular assemblies from specimens preserved in vitreous ice. Ultimately we plan to develop an integrated system that can produce an electron density map of a structure within a few hours of inserting a specimen into the electron microscope. With this goal in mind it is essential that the images be acquired using a digital camera rather than film.
