Biopharmaceutical Research with Electron Microscopy

Bio-pharma drug discovery through high resolution cryo-electron microscopy.


Rather than starting with a disease and searching for its origin, protein-based biopharmaceuticals (biologics) begins with the detection of a genetic variation and then relies on therapies that manipulate it. Cryo-EM helps researchers examine a broad range of biological structures and provides the ability to visualize otherwise difficult or complicated biologics.

For example, protein samples, which are frozen in vitreous (non-crystalline) ice, can be examined in a near-native, fully hydrated state, thereby enabling accelerated structural drug discovery. Near-atomic-resolution cryo-electron microscopy can be employed throughout the drug discovery process, from target identification, through lead characterization, to epitope mapping.

Techniques

Single Particle Analysis

Single particle analysis (SPA) is a cryo-electron microscopy technique that enables structural characterization at near-atomic resolutions, unraveling dynamic biological processes and the structure of biomolecular complexes/assemblies.

Cryo-Tomography

Cryo-electron tomography (cryo-ET) delivers both structural information about individual proteins as well as their spatial arrangements within the cell. This makes it a truly unique technique and also explains why the method has such an enormous potential for cell biology. Cryo-ET can bridge the gap between light microscopy and near-atomic-resolution techniques like single-particle analysis.

MicroED

MicroED is an exciting new technique with applications in the structural determination of small molecules and protein. With this method, atomic details can be extracted from individual nanocrystals (<200 nm in size), even in a heterogeneous mixture.
